Correct answer: C. 3 ATP

  • A. 1 ATP
  • B. 2 ATP
  • C. 3 ATP
  • D. 4 ATP

Explanation

The oxidation of one molecule of NADH thus leads to the synthesis of three molecules of ATP, whereas the oxidation of FADH2, which enters the electron transport chain at complex II, yields only two ATP molecules.
