Question

Which step produces the most ATP?

Answer 1

Oxidative phosphorylation

1. Oxidative phosphorylation is the step that produces the most ATP.
2. It is also known as the electron transport chain.
3. It involves ATP synthesis by the coupled movement of electrons in mitochondria.
4. It is an oxygen-dependent reaction.
5. In oxidative phosphorylation electrons from NADH and FADH₂ are transferred to molecular oxygen, coupled to the formation of an additional 32 to 34 ATP molecules.
