During the catabolism of a certain amino acid, 10 molecules of NADH and 4 molecules of FADH₂ are produced. How many molecules of ATP can produced when the coenzymes are oxidized in the mitochondria?

Question

Quizplus · Accepted Answer

Each NADH molecule produces approximately 2.5 ATP, and each FADH2 molecule produces approximately 1.5 ATP. Therefore, 10 NADH produce 25 ATP (10 x 2.5), and 4 FADH2 produce 6 ATP (4 x 1.5), totaling 31 ATP.
