Out of the following given choices;
1) Oxygen would no longer be required for ATP production.
2) ATP production would increase rapidly.
3) Carbon dioxide would no longer be made as a result of ATP production.
4) ATP production would stop.
The answer is 2. This is due to the fact that ATP synthase is responsible for synthesis of ATP during chemiosomosis. IT utilizes the electromotive force by the proton gradient across the mitochondrial membrane to phosphorylate ADP to ATP.
