Since acetyl-CoA has 2 carbons, a 16 carbon fatty acid will produce 8 acetyl-CoAs, 8 FADH2s, 8 NADHs, and use 8 waters. 網頁Each —CH2—CH2— unit yields 14 extra ATP molecules. The two oxidations of the b-oxidation pathway produce 1 FADH2 and 1 NADH, which yield 1.5 and 2.5 ATP, respectively, by oxidative phosphorylation. The extra acetyl-CoA, when oxidized via the citric acid cycle, yields another 10 ATP equivalents: 3 NADH, 1 FADH2, and 1 ATP or GTP. rnc winter meeting
