Question

Quizplus · Accepted Answer

The TCA cycle primarily breaks down acetyl CoA, which can be derived from fatty acids or glucose via pyruvate. Glycerol from triglycerides can also be converted to glucose or pyruvate for use in the TCA cycle. Amino acids can also be converted to pyruvate or directly enter the TCA cycle. Therefore, the best choice is C, which includes fatty acids, glycerol, and amino acids as substances that can enter the TCA cycle directly or through pyruvate/acetyl CoA.
