Electrons from NADH accepted by oxygen form how many ATPs?
Correct answer: B. 3
- A. 1
- B. 3
- C. 4
- D. 2
Explanation
In the electron transport chain, each NADH donates electrons that ultimately reduce oxygen to water. During this process, enough energy is released to produce approximately 3 molecules of ATP through oxidative phosphorylation.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
