Answer 1

1. Adenosine triphosphate is the power house of a living body or cells of animals. It gets produced via electron transport chain with the help of oxygen being the acceptor of electron to produce water. If cellular respiration machinery get stopped, there will be no generation of ATP, which eventually causes cessation of all cellular activity and death of the cells as well as death of the animal body.

4. A. The rate of formation of ATP will be decreased. According to chemiosmotic theory the H+ gradient helps to rotate the F1-F0 units in the mitochondrial membrane to produce ATP. if the gradient gets lost, the ATP formation mechanism will stop and the energy will be lost as heat.

B. As there is lose of energy in the form of heat, cells will try to compensate and try to produce energy to meet the cellular requirement. Thus rate of electron transport chain reaction will increase.

C. As the rate of ETC increases, the use of oxygen to accept the electron will also increase.

D. As cells require energy to survive, and glucose is the most common substrate to be used by the cell, oxidation of glucose will increase in this case.
