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.
