[{'content': 'Which of the following is produced by the complete oxidation one molecule of palmitic acid in mitochondrial beta oxidation? \nSelect and explain. \nA. 8 FADH2, 8 NADH and 8 acetyl CoA molecules, B. 7 FADH2, 7 NADH and 7 acetyl CoA molecules, C. 8 FADH2, 8 NADH and 7 acetyl CoA molecules, D. 7 FADH2, 7 NADH and 8 acetyl CoA molecules', 'role': 'user'}, {'content': 'Answer: D \nExplanation: Palmitic acid is a 16-carbon fatty acid. Acetyl-CoA is a 2-carbon molecule. So, oxidation of palmitate should produce 8 acetyl-CoA molecules. -> option b and c are directly excluded. One may think that there will be 8-rounds of beta oxidation. But there are only 7-rounds since the 7th round produces two acetyl-CoA molecules. So, 7 FADH2 and 7 NADH are produced. -> option a is excluded.', 'role': 'assistant'}]
