Verified by Experts

The Calculations of the net gain of ATP for every glucose molecules oxidised can be made on the following assumptions
(i) There is sequential pathway that follows. i.e., glycolysis , TCA cycle and ETS in cytoplasm , mitochndrial matrix and inner mitochonodrial membrane respectively.
(ii) NADH, synthesised in glycolysis enters in to ETC for phosphorylation.
(iii) None of the intermediates in the pathway are utlised to synthesis any other compound
(iv) Glucose forms respiatory substrate.
These assumptions are not valid for a living system because of following neasons
(i) These all pathways work simultaneously and do not take place one after the other.
(ii) ATP is utilised when needed.
(iii) Rate of enzyme actions is controlled by multiple means.
Comparisan between fermentation and aerobic respiration are as follows
`{:("Fermentation","Aerobic Respirartion"),("Fermentation is partial breakdown of glucose.","It is complete breakdown of glucose"),("Net gain of only "2ATP,38 ATP " are produced"),("Oxidation of NADH to " NAD^(+) " is slow proces","It is vigorous reaction in aerobic respiration"):}`

You have two passages with 5 questions following each passage. Read the passage carefully and choose the best answer to each question out of the four alternatives and mark it by blackening the appropriate oval in the Answer Sheet. PASSAGE-1 The public distribution system, which provides food at low prices, is a subject of vital concern. There is a growing realization that though India has enough food to feed its masses two square meals a day, the monster of starvation and food insecurity continues to haunt the poor in our country. Increasing the purchasing power of the poor through providing productive employment leading to rising income, and thus good standard of living, is the ultimate objective of public policy. However, till then, there is a need to provide assured supply of food through a restructured, more efficient and decentralized public distribution system (PDS). Although the PDS is extensive - it is one of the largest such systems in the world - it hasn.t reached the rural poor and the remote places. It remains an urban phenomenon, with the majority of the rural poor still out of its reach due to lack of economic and physical access. The poorest in the cities and the migrants are left out, for they generally do not possess ration cards. The allocation of PDS supplies in big cities is larger than in rural areas. In view of such deficiencies in the system, the PDS urgently needs to be streamlined. Also, considering the large food grains production combined with food subsidy on one hand and the continuing slow starvation and dismal poverty of rural population on the other, there is a strong case for making PDS target group oriented. By making PDS target group oriented, not only the poorest and the neediest would be reached without additional cost but we can also reduce the overall costs incurred. What should be an appropriate step to make the PDS effective?

The assault on the purity of the environment is the price that we pay for many of the benefits of modern technology. For the advantages of automotive transportation we pay a price in smog-induced diseases, for the powerful effects of new insecticides, we pay a price in dwindling wildlife and disturbances in the relation of living things and their surroundings, for nuclear power, we risk the biological hazards of radiation. By increasing agricultural production with fertilizers, we increase water pollution. The highly developed nations of the world are not only the immediate beneficiaries of the good that technology can do, they are also the first victims of the environmental diseases that technology breeds. In the past, the environmental effects which accompanied technological progress were restricted to a small place and relatively a short time. The new hazards are neither local nor brief. Modern air pollution covers vast areas of continents. Radioactive fallout from nuclear explosions is. worldwide. Radioactive pollutants now on the Earth's surface will be found there for generations, and in the case of Carbon-14, for thousands of years. With reference to the passage, the following assumptions have been made : 1. The widespread use of insecticides has caused ecological imbalance. 2. Conservation of natural flora and fauna is impossible in this age of modern technology Which of the assumptions is/are valid ?
