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.
