Explanation:
(c) Krebs cycle (also called as tricarboxylic acid cycle, TCA) is amphibolic or having both catabolic and anabolic rates, for e.g. acetyl CoA entering the cycle is completely broken down to form $\text{C}{{\text{O}}_{2}}$ and hydrogen showing catabolic role. In anabolic role, acetyl COA is related to synthesis and breakdown of fatty acids, steroids, carotenoids, terpenes and aromatic compounds.
