Which of the above is/are the emission/ emissions from coal combustion at thermal power plants?
(a) 1 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3 only
Explanation : (Answer : d)
By products of power thermal plant operation need to be considered in both the design and operation. Waste heat due to the finite efficiency of the power cycle must be released to the atmosphere, using a cooling tower, or river or lake water as a cooling medium. The flue gas from combustion of the fossil fuels is discharged to the air; this contains carbon dioxide and water vapour, as well as other substances such as nitrogen, nitrogen oxides, sulfur oxides, and (in the case of coal-fired plants) fly ash, mercury and traces of other metals. Solid waste ash from coal-fired boilers must also be removed. Some coal ash can be recycled for building materials.
3. Satellites used for telecommunication relay are kept in a geostationary orbit. A satellite is said to be in such an orbit when:

2. The orbit is circular
3. The orbit lies in the plane of the Earth‘s equator.
4. The orbit is at an altitude of 22.236 km.
Select the correct answer using the codes given below:
(a) 1, 2 and 3 only
(b) 1, 3 and 4 only
(c) 2 and 4 only
(d) 1, 2, 3 and 4
Explanation (Answer : d)
A geostationary orbit (or Geostationary Earth Orbit - GEO) is a geosynchronous orbit directly above the Earth’s equator (0° latitude), with a period equal to the Earth’s rotational period and an orbital eccentricity of approximately zero.
An object in a geostationary orbit appears motionless, at a fixed position in the sky, to ground observers. Communications satellites and weather satellites are often given geostationary orbits, so that the satellite antennas that communicate with them do not have to move to track them, but can be pointed permanently at the position in the sky where they stay. Due to the constant 0° latitude and circularity of geostationary orbits, satellites in GEO differ in location by longitude only.
It is the part of space about 35,786 km (22,000 mi) above sea level, in the plane of the equator, where near-geostationary orbits may be implemented.
Geostationary orbits are useful because they cause a satellite to appear stationary with respect to a fixed point on the rotating Earth, allowing a fixed antenna to maintain a link with the satellite. The satellite orbits in the direction of the Earth’s rotation, at an altitude of 35,786 km (22,236 mi) above ground, producing an orbital period equal to the Earth’s period of rotation, known as the sidereal day.

1. They use living organisms as catalysts to generate electricity from certain substrates.
2. They use a variety of inorganic materials as substrates.
3. They can be installed in waste water treatment plants to cleanse water and produce electricity.
Which of the statements given above is/are correct?
(a) 1 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3
Explanation : (Answer : c)
The idea of using microbial cells in an attempt to produce electricity was first conceived at the turn of the nineteenth century. M.C. Potter was the first to perform work on the subject in 1911. A microbial fuel cell is a device that converts chemical energy to electrical energy by the catalytic reaction of microorganisms.
A typical microbial fuel cell consists of anode and cathode compartments separated by a cation (positively charged ion) specific membrane. In the anode compartment, fuel is oxidized by microorganisms, generating electrons and protons. Electrons are transferred to the cathode compartment through an external electric circuit, while protons are transferred to the cathode compartment through the membrane. Electrons and protons are consumed in the cathode compartment, combining with oxygen to form water.
More broadly, there are two types of microbial fuel cell: mediator and mediator-less microbial fuel cells.
Since the current generated from a microbial fuel cell is directly proportional to the energy content of wastewater used as the fuel, an MFC can be used to measure the solute concentration of wastewater (i.e. as a biosensor system).
The strength of wastewater is commonly evaluated as biochemical oxygen demand (BOD) values.
8. Which one of the following statements appropriately describes the fiscal stimulus ?
(a) It is a massive investment by the Government in manufacturing sector to ensure the supply of goods to meet the demand surge caused by rapid economic growth.
(b) It is an intense affirmative action of the Government to boost economic activity in the country.
(c) It is Government‘s intensive action on financial institutions to ensure disbursement of loans to agriculture and allied sectors to promote greater food production and contain food inflation.
(d) It is an extreme affirmative action by the Government to pursue its policy of financial inclusion.
Explanation : (Answer : b)
Governments use fiscal policy to influence the level of aggregate demand in the economy, in an effort to achieve economic objectives of price stability, full employment, and economic growth. Keynesian economics suggests that increasing government spending and decreasing tax rates are the best ways to stimulate aggregate demand. This can be used in times of recession or low economic activity as an essential tool for building the framework for strong economic growth and working towards full employment. In theory, the resulting deficits would be paid for by an expanded economy during the boom that would follow; this was the reasoning behind the New Deal.
Governments can use a budget surplus to do two things: to slow the pace of strong economic growth, and to stabilize prices when inflation is too high. Keynesian theory posits that removing spending from the economy will reduce levels of aggregate demand and contract the economy, thus stabilizing prices.
Economists debate the effectiveness of fiscal stimulus. The argument mostly centers on crowding out, a phenomenon where government borrowing leads to higher interest rates that offset the stimulative impact of spending. When the government runs a budget deficit, funds will need to come from public borrowing (the issue of government bonds), overseas borrowing, or monetizing the debt. When governments fund a deficit with the issuing of government bonds, interest rates can increase across the market, because government borrowing creates higher demand for credit in the financial markets. This causes a lower aggregate demand for goods and services, contrary to the objective of a fiscal stimulus. Neoclassical economists generally emphasize crowding out while Keynesians argue that fiscal policy can still be effective especially in a liquidity trap where, they argue, crowding out is minimal.
9. The formation of ozone hold I the Antarctic region has been a cause of concern. What could be the reason for the formation of this hole?
(a) Presence of prominent tropospheric turbulence; and inflow of chlorofluorocarbons.
(b) Presence of prominent polar front and stratospheric clouds; and inflow of chlorofluorocarbons.
(c) Absence of polar front and stratospheric clouds; and inflow of methane and chlorofluorocarbons.
(d) Increased temperature at polar region due to global warming.
Explanation : (Answer : b)
Methane is not responsible for ozone hole, its only responsible for Global Warming.
The chemistry of the Antarctic polar vortex has created severe ozone depletion. The nitric acid in polar stratospheric clouds reacts with CFCs to form chlorine, which catalyzes the photochemical destruction of ozone. Chlorine concentrations build up during the winter polar night, and the consequent ozone destruction is greatest when the sunlight returns in spring (September/October). These clouds can only form at temperatures below about -80°C. Since these temperatures are rarely reached in the Arctic, ozone depletion at the north pole is much less severe than at the south. Accordingly, the seasonal reduction of ozone levels over the Arctic is characterized as an “ozone dent,” whereas the more severe ozone depletion over the Antarctic is considered an “ozone hole

15. Regarding carbon credits , which one of the following statements is not correct?
(a) The carbon credit system was ratified in conjunction with the Kyoto Protocol
(b) Carbon credits are awarded to countries or groups that have reduced greenhouse gases below their emission quota.
(c) The goal of the carbon credit system is to limit the increase of carbon dioxide emission.
(d) Carbon credits are traded at a price fixed from time to time by the United nations Environment Programme.
Explanation : (Answer : d)
Under the Kyoto Protocol, the ‘caps’ or quotas for Greenhouse gases for the developed Annex 1 countries are known as Assigned Amounts and are listed in Annex
B. The quantity of the initial assigned amount is denominated in individual units, called Assigned amount units (AAUs), each of which represents an allowance to emit one metric tonne of carbon dioxide equivalent, and these are entered into the country’s national registry
Developed country can ‘sponsor’ a greenhouse gas reduction project in a developing country where the cost of greenhouse gas reduction project activities is usually much lower, but the atmospheric effect is globally equivalent. The developed country would be given credits for meeting its emission reduction targets, while the developing country would receive the capital investment and clean technology or beneficial change in land use.

20. Three of the following criteria have contributed to the recognition of Western Ghats-Sri Lanka and Indo-Burma regions as hotspots of biodiversity:
1. Species richness
2. Vegetation density
3. Endemism
4. Ethno-botanical importance
5. Threat perception
6. Adaption of flora and fauna to warm and humid conditions.
Which three of the above are correct criteria in this context?
(a) 1, 2 and 6
(b) 2, 4 and 6
(c) 1, 3 and 5
(d) 3, 4 and 6
Explanation : (Answer : c)
The total number of plants that are endemic to an area is one of the two primary criteria for determining biodiversity hotspot status. To be designated as a hotspot, an area must have at least 1,500 species of endemic plants. Many hotspots exceed this number by thousands. Sundaland and the Tropical Andes, for example, each have 15,000 endemic plants. In total, hotspots hold at least 150,000 plants as endemics, representing a remarkable 50 percent of the world‘s vascular plant species. This is an absolute minimum, because it does not include species that are endemic to the combined area of two or more hotspots.
Another form of measurement, which is perhaps a better indicator of the importance of a particular hotspot, is the percentage of endemic plants compared to a hotspot‘s total plant diversity. For example, among the 13,000 plants species found in Madagascar and the Indian Ocean Islands, 11,600 are endemics, a remarkable 89 percent. These data are given in each of the individual hotspot sections

3. The oils used are not likely to damage the cardiovascular health of the consumers.
Which of the statements given above is/are above?
(a) 1 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3
Explanation : (Answer : d)
No trans fats are essential fatty acids; indeed, the consumption of trans fats increases the risk of coronary heart disease by raising levels of “bad” LDL cholesterol and lowering levels of “good” HDL cholesterol. Health authorities worldwide recommend that consumption of trans fat be reduced to trace amounts. Trans fats from partially hydrogenated oils are more harmful than naturally occurring oils.
A type of trans fat occurs naturally in the milk and body fat of ruminants (such as cattle andsheep) at a level of 2–5% of total fat. Natural trans fats, which include conjugated linoleic acid(CLA) and vaccenic acid, originate in the rumen of these animals.
The primary health risk identified for trans fat consumption is an elevated risk of coronary heart disease (CHD). A comprehensive review of studies of trans fats was published in 2006 in the New England Journal of Medicine reports a strong and reliable connection between trans fat consumption and CHD, concluding that “On a per-calorie basis, trans fats appear to increase the risk of CHD more than any other macronutrient, conferring a substantially increased risk at low levels of consumption (1 to 3% of total energy intake)”
Unsaturated fat is a fat molecule containing one or more double bonds between the carbon atoms. Since the carbons are double-bonded to each other, there are fewer bonds connected to hydrogen, so there are fewer hydrogen atoms, hence “unsaturated”. Cis and trans are terms that refer to the arrangement of chains of carbon atoms across the double bond. The process of hydrogenation adds hydrogen atoms to unsaturated fats, eliminating double bonds and making them into partially or completely saturated fats. However, partial hydrogenation, if it is chemical rather than enzymatic, converts a part of cis-isomers into trans-unsaturated fats instead of hydrogenating them completely.

Which of the above is/are Human Right/Human Rights under Universal Declaration of Human Rights ?
(a) 1 only
(b) 1 and 2 only
(c) 3 only
(d) 1, 2 and 3
Explanation : (Answer : d)
The Universal Declaration of Human Rights (UDHR) is a declaration adopted by the United Nations General Assembly (10 December 1948 at Palais de Chaillot, Paris). The Declaration arose directly from the experience of the Second World War and represents the first global expression of rights to which all human beings are inherently entitled. It consists of 30 articles which have been elaborated in subsequent international treaties, regional human rights instruments, national constitutions and laws. The International Bill of Human Rights consists of the Universal Declaration of Human Rights, theInternational Covenant on Economic, Social and Cultural Rights, and the International Covenant on Civil and Political Rights and its two Optional Protocols.
Article 21
(1) Everyone has the right to take part in the government of his country, directly or through freely chosen representatives.
(2) Everyone has the right to equal access to public service in his country.
(3) The will of the people shall be the basis of the authority of government; this will shall be expressed in periodic and genuine elections which shall be by universal and equal suffrage and shall be held by secret vote or by equivalent free voting procedures
Article 25
(1) Everyone has the right to a standard of living adequate for the health and wellbeing of himself and of his family, including food, clothing, housing and medical care and necessary social services, and the right to security in the event of unemployment, sickness, disability, widowhood, old age or other lack of livelihood in circumstances beyond his control.
Article 26
(1) Everyone has the right to education. Education shall be free, at least in the elementary and fundamental stages. Elementary education shall be compulsory. Technical and professional education shall be made generally available and higher education shall be equally accessible to all on the basis of merit.
(2) Education shall be directed to the full development of the human personality and to the strengthening of respect for human rights and fundamental freedoms. It shall promote understanding, tolerance and friendship among all nations, racial or religious groups, and shall further the activities of the United Nations for the maintenance of peace.
(3) Parents have a prior right to choose the kind of education that shall be given to their children
47. There is a concern over the increase in harmful algal blooms in the seawaters of India: What could be the causative factors for this phenomenon?
1. Discharge of nutrients from the estuaries
2. Run-off from the land during the monsoon.
3. Upwelling in the seas.
Select the correct answer from the codes given below:
(a) 1 only
(b) 1 and 2 only
(c) 2 and 3 only
(d) 1, 2 and 3
Explanation : (Answer : d)
Like land plants, algae need certain things to grow – water, carbon dioxide, sunlight and nutrients. Carbon dioxide is plentiful in the marine environment, but sunlight and nutrients can be scarce. Sunlight is available near the surface of the water, so algae grow readily when they can remain near the surface. Nutrients are abundant in areas of run-off where water flows over land and picks up minerals that are then carried to the sea. Nutrients are also plentiful in areas where cool, deep, nutrient-rich waters are brought to the surface due to upwelling, tides or wind-driven mixing. When the algal cells get everything they need to grow, they can divide very rapidly and potentially create a bloom.
Surface runoff from farming, as well as urban runoff and runoff from the construction of roads, buildings, ports, channels, and harbours, can carry soil and particles laden with carbon, nitrogen, phosphorus, and minerals. This nutrient-rich water can cause fleshy algae and phytoplankton to thrive in coastal areas; known as algal blooms, which have the potential to create hypoxic conditions by using all available oxygen.
48. Consider the following
1. Photosynthesis
2. Respiration
3. Decay of organic matter
4. Volcanic action
Which of the above add carbon dioxide to the carbon cycle on Earth?
(a) 1 and 4 only
(b) 2 and 3 only
(c) 2, 3 and 4 only
(d) 1, 2, 3 and 4
Explanation : (Answer : c)
Photosynthesis : Wrong - Photosynthesis by plants removes about 120 billion tons of carbon from the air per year, but plant decomposition returns about the same amount. Photosynthesis (synthesizing starches and sugars using light) is a main mechanism for cycling carbon by the biosphere.
CH2O represents a unit of organic matter; six of the CH2O unit would be C6H1206 which makes the simple sugar (glucose or fructose) and 11 of these units make C11H22O11, a more complex sugar, sucrose, formed by the combination of one glucose and one fructose. Thousands of glucose molecules combine to form a molecule of starch, or of cellulose. (Molecule examples) Thus photosynthesis takes the atmospheric carbon in CO2 and “fixes” it into the biosphere. The subsequent cycling of the carbon in the biomass is created.
Respiration : When the organic matter is oxidized through respiration, the reverse of photosynthesis takes place.
Respiration releases CO2 into the atmosphere. Respiration and photosynthesis occur at nearly equal rates over one year.
The sediments including fossil fuels.
Volcanic Ash: Volcanic eruptions and metamorphism release gases into the atmosphere. Volcanic gases are primarily water vapor, carbon dioxide and sulfur dioxide. The carbon dioxide released is roughly equal to the amount removed by silicate weathering [citation needed]; so the two processes, which are the chemical reverse of each other, sum to roughly zero, and do not affect the level of atmospheric carbon dioxide on time scales of less than about 100,000 years.
Carbon moves into the atmosphere from decomposition of 1.organic matter, 2.respiration by living organisms, 3.combustion, 4.volcanic activity,5. burning fossil fuels, 6.degassing of waterbodies, etc.
49. Recently, the USA decided to support India‘s membership in multi-lateral export control regimes called the Australia Group and the Wassenaar Arrangement What is the difference between them?

2. The Australia group Comprises predominantly of Asian, African and North American countries, whereas the members countries of wassenaar Arrangement are predominantly from the European Union and American Continents
Which of the statements given above is/are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Explanation : (Answer : a)
The principal objective of Australia Group participants‘ is to use licensing measures to ensure that exports of certain chemicals, biological agents, and dual-use chemical and biological manufacturing facilities and equipment, do not contribute to the spread of CBW. The Group achieves this by harmonising participating countries‘ national export licensing measures. The Wassenaar Arrangement was formally approved by 33 countries,including 27 of the 29 OECD Member countries, in July 1996. Prior to it‘s final adoption, the interim agreement was provisionally called the New Forum . The Wassenaar Arrangement is a collaboration of countries that defines a set of preliminary guidelines covering both armaments and sensitive dual-use goods and technologies which need to be fully implemented at the national level. It focuses on threats to international and regional peace and security by providing for greater openness through information sharing about arms, dual-use goods and technology transfers world-wide.
Australia Group Established in 1985 Membership: 41 Members — Argentina, Australia, Austria, Belgium, Bulgaria, Canada, Croatia, Cyprus, Czech Republic, Denmark, Estonia, European Union, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Japan, Republic of Korea, Latvia, Lithuania, Luxembourg, Malta, Netherlands, New Zealand, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey, Ukraine, United Kingdom, and United States.

(c) The density of water is maximum at 4°C
(d) None of the statements (a), (b) and (c) given above is correct
Explanation : (Answer : d)
When temperature starts reducing in winter, lake water cools upto 4degree centegrade by convection as density increase with reduction in temp.On futher cooling, due to abnoamal expansion og water , density reduces & cold water remains at top .Then top layer frezees.Water being bad conductor of heat ,lake water below ice remains at 4 degrees & thus fishes sruvive in winter aslo
51. A sandy and saline area is the natural habitat of an Indian animal species. The animal has no predators in that area but its existence is threatened due to the destruction of its habitat. Which one of the following could be that animal?
(a) Indian wild buffalo
(b) Indian wild ass
(c) Indian wild boar
(d) Indian gazelle
Explanation : (Answer : b)
The Indian wild ass also called khur, is a subspecies of the Onagernative to Southern Asia. The Indian wild ass, as with most other Asian wild ass subspecies, is quite different from theAfrican species. The coat is usually sandy, but varies from reddish grey, fawn, to pale chestnut. The Indian wild ass’s range once extended from western India, through Sindh and Baluchistan, Afghanistan, and south-eastern Iran. Today, its last refuge lies in the Indian Wild Ass Sanctuary, Little Rann of Kutch and its surrounding areas of the Greater Rann of Kutch in the Gujarat province.
The animal, however, is also seen in the districts of Surendranagar, Banaskantha, Mehsana, and other Kutch districts. Saline desert, grassland in arid zone and shrubland are its preferred homeland. It is unknown how the Indian wild ass disappeared from its former haunts in parts of western India and Pakistan, since the animal was never a hunting target of Indian Maharajas and colonial British officials of the British Raj. From 1958-1960, the wild ass became a victim of a disease known as surra, caused by Trypanosoma evansi and transmitted by flies, which caused a dramatic decline of its population in India. Besides disease, the ass’s other threats include habitat degradation due to salt activities, the invasion of the Prosopis juliflora shrub, and encroachment and grazing by the Maldhari.
52. La Nina is suspected to have caused recent floods in Australia. How is LaNina different from El Nino?
1. La Nina is characterized by unusually cold ocean temperature in equatorial Indian Ocean whereas El Nino is characterized by unusually warm ocean temperature in the equatorial Pacific Ocean.
2. El Nino has adverse effect on south-west monsoon of India, but La Nina has no effect on monsoon climate
Which of the statement given above is/are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Explanation : (Answer :d)
La Niña is a coupled ocean-atmosphere phenomenon that is the counterpart of El Niño as part of the broader El Niño-Southern Oscillation climate pattern. During a period of La Niña, the sea surface temperature across the equatorial Eastern CentralPacific Ocean will be lower than normal by 3–5 °C. In the United States.
A La Niña, on the other hand, is often beneficial for the monsoon, especially in the latter half. The La Niña that appeared in the Pacific in 2010 probably helped last year’s south-west monsoon end on the favourable note.

(a) It was a non-violent movement
(b) It was led by Mahatma Gandhi
(c) It was a spontaneous movement
(d) It did not attract the labour class in general
Explanation : (Answer : b)
True -On August 8, 1942 the Quit India Resolution was passed at the Bombay session of the All India Congress Committee (AICC). In a speech at Gowalia Tank, Bombay, Gandhi told Indians to follow non-violent civil disobedience. He told the masses to act as an independent nation.
Untrue - Gandhi launched the Quit India Movement in 1942, demanding immediate independence for India. The entire Congress leadership, and not merely at the national level, was put into confinement less than twenty-four hours after Gandhi’s speech, and the greater number of the Congress leaders were to spend the rest of the war in jail.

61. Biodiversity forms the basis for human existence in the following ways:
1. Soil formation
2. Prevention of soil erosion
3. Recycling of waste
4. Pollination of crops
Select the correct answer using the codes given below:
(a) 1, 2 and 3 only
(b) 2, 3 and 4 only
(c) 1 and 4 only
(d) 1, 2, 3 and 4
Explanation : (Answer d)
Biological diversity helps in the formation and maintenance of soil structure and the retention of moisture and nutrient levels. The loss of biological diversity through clearing of vegetation has contributed to the salinisation of soils, leaching of nutrients, laterisation of minerals and accelerated erosion of topsoil, reducing the land’s productivity. Trees, on the other hand, lower the water table and remove deposited salt from the upper soil horizons.
Soil protection by maintenance of biological diversity can preserve the productive capacity of the soil, prevent landslides, safeguard coastlines and riverbanks, and prevent the degradation of coral reefs and coastal fisheries by siltation.
Trees and other vegetation also assist in soil formation. A significant contribution is the introduction of organic matter through litter formation and the decay and regeneration of tiny fibrous roots, both of which facilitate microbial activity. Another contribution is through the effects of root systems which break up soil and rock leading to, amongst other things, penetration of water. Root systems also bring mineral nutrients to the surface through root uptake. Organic matter formed by the decay of tiny fibrous roots can also bind with minerals, such as iron and aluminium, which can reduce the potential deleterious effects of these minerals on other vegetation
Biodiversity supports ecosystem services including air quality, climate (e.g., CO2sequestration), water purification, pollination, and prevention of erosion
Biodiversity supports many ecosystem services that are often not readily visible. It plays a part in regulating the chemistry of our atmosphere and water supply. Biodiversity is directly involved inwater purification, recycling nutrients and providing fertile soils.

64. What is the difference between a CFL and an LED lamp ?
1. To produce light, a CFL uses mercury vapour and phosphor while an LED lamp uses semi-conductor material.
2. The average life span of a CFL is much longer than that of an LED lamp.
3. A CFL is less energy-efficient as compared to an LED lamp.
Which of the statements given above is/are correct ?
(a) 1 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2, and 3
Explanation : (Answer : c)
Fluorescent lamps (light bulbs) work by passing electricity through mercury vapor, which in turn emits ultraviolet light. The ultraviolet light is then absorbed by a phosphor coating inside the lamp, causing it to glow, or fluoresce.
CFLs typically have a rated lifespan of between 6,000 and 15,000 hours, A LED light bulb can be expected to last 25–30 years under normal use.
A single LED is a low-voltage solid state device and cannot be directly operated on standard AC current without some circuitry to control the voltage applied and the current flow through the lamp. A series diode and resistor could be used to control the voltage polarity and to limit the current, but this is inefficient since most of the applied voltage would be dropped as wasted heat in the resistor. LEDs are small, solid light bulbs which are extremely energy-efficient. New LED bulbs are grouped in clusters with diffuser lenses which have broadened the applications for LED use in the home.
65. Recently, oilzapper was in the news. What is it?

(c) They neutralize the free radicals produced in the body during metabolism
(d) They active certain genes in the cells of the body and help delay the ageing process
Explanation : (Answer : c)
Oxidation reactions can produce free radicals. In turn, these radicals can start chain reactions. When the chain reaction occurs in a cell, it can cause damage or death. When the chain reaction occurs in a purified monomer, it produces a polymer resin, such as a plastic, a synthetic fiber, or an oil paint film. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions. They do this by being oxidized themselves, so antioxidants are often reducing agents such as thiols, ascorbic acid orpolyphenols.
