If instead of glucose, your cell uses a C-18 fatty acid as an energy source. How many NADH, FAHD_2 and ATP molecules will you get per C-18 fatty acid molecule? Assume the C-18 molecule is completely catabolized to acetyl CoA; that is all carbon atoms are incorporated into acetyl CoA. 27 NADH, 9 ATP, 9 FAHD_2 12 NADH, 4 FAHD_2, 4 ATP 18 NADH, 4 ATP, 6 FAHD_2 36 NADH, 9 FAHD_2, 9 ATP 6 NADH, 2 FAHD_2, 2 ATP
