WebThe TCA cycle is amphibolic; that is, it serves as a catabolic and an anabolic pathway. Reactions that utilize intermediates of the cycle as precursors for the biosynthesis of other molecules are listed below. Some of these reactions occur outside the mitochondria. 1. Citrate+ATP+CoA→acetyl-CoA+oxaloacetate+ADP+P i. WebThe Citric Acid Cycle 5 Step-wise reactions of the TCA cycle 1. Aldol condensation of oxaloacetate with acetylCoA followed by hydrolysis of CoASH to give citrate. Enzyme: citrate synthase. This is the first irreversible step 2. Dehydration followed by hydration leads to interchange of -H and –OH and isomerization of citrate to isocitrate.
