Homework Answers
1 NADH produces 2.5 ATP molecule so total ATP = 58 * 2.5 = 145 ATP.
1 FADH2 produces 1.5 ATP molecule so total ATP = 19 * 1.5 = 28.5 ATP.
so total ATP = 145 + 28.5 = 173.5 ATP

A fatty acid composed of 20 carbon atoms undergoes β‑oxidation. How many acetyl CoA, FADH2, and NADH does β‑oxidation of this fatty acid generate? (answer is 10 acetyl CoA, 9 FADH2, 9 NADH) Calculate the net ATP generated by the β‑oxidation of the 20‑carbon fatty acid. Assume that each FADH2 generates 1.5 ATP and each NADH generates 2.5 ATP. number of ATP molecules: ??????
