Quizplus · Accepted Answer

Lauric acid has 12 carbons and undergoes beta oxidation to produce 7 FADH2 and 7 NADH molecules, which enter the electron transport chain to produce 28 ATP. In addition, the 12-carbon molecule produces 8 acetyl-CoA molecules, which enter the Krebs cycle to produce 80 ATP. Therefore, the total ATP production from one lauric acid molecule is (28 ATP + 80 ATP) = 108 ATP, but two ATP were used in the activation of the fatty acid, so the net production is (108 ATP - 2 ATP) = 106 ATP, which rounded to the closest value is 78 ATP.
