50. How are fats converted into energy through cellular respiration pathways? (A) Fatty acids are converted to pyruvate in the cytosol and then enter the mitochondria. (B) Fatty acids undergo beta-oxidation to produce acetyl-CoA, which enters citric acid cycle. (C) The entire fat molecule is converted into an intermediate of glycolysis. (D) Glycerol enters the citric acid cycle directly, while fatty acids are converted to glucose. (E) Fats are converted to NADH and FADH2 without entering glycolysis or citric acid cycle.
