Question
Your group has 8 glucose molecules and 7 triglyceride molecules. There is plenty of oxygen so all of your substrate will undergo oxidative phosphorylation. Start with your glucose molecules and trace them through glycolysis, the Krebs cycle, and the electron transport chain. Remember that 2 pyruvate are produced from each glucose molecule. The triglyceride is composed of a glycerol and 3 fatty acid chains of palmitic acid (a 16 carbon saturate fatty acid). Your triglyceride molecules will go through beta-oxidation. The end product of beta-oxidation is acety CoA. For each fatty acid chain that goes through beta-oxidation, 8 acetyl-CoA, 7 NADH, and 7 FADH are produced The acetyl-CoA that is produced from beta-oxidation will then enter the Krebs cycle, while the NADH and FADH produced during beta-oxidation will go directly to the electron transport chain. Remember, there are 3 fatty acio chains on each triglyceride molecule.Explanation / Answer
Per glucose molecule yields 10 NADH and 2 FADH molecules and 30 ATP by the time they enter oxidative phosphorylation.
Per saturated even fatty acid gives 7 FADH, 7 NADH,8 acetyl-CoA and 106 ATP.
Hence 3 molecules of fatty acid gives 21 FADH,21 NADH, 24 acetyl-CoA and 318 ATP
22. total NADH=10*8+7*21=227
23.total FADH=8*2+21*7=163
24.net ATP=8*30+318*7=2466
