Question

Oxidation of one molecule of NADH gives ______.

• A. 3 ATP molecules
• B. 12 ATP molecules
• C. 1 ATP molecule
• D. 8 ATP molecules

Answer 1

The correct option is A 3 ATP molecules

Oxidation of one molecule of NADH gives rise to 3 ATP molecules, 2.5 molecules of ATP to be exact according to recent research. The fraction is because ATP production is actually linked to the chemiosmotic diffusion of protons across the proton gradient, rather than a single reaction.
