1 Jom L C Tegulation TCA cycle (Ch. 16) 1. The citric acid cycle has eight enzymes: citrate synthase, aconitase, isocitrate dehydrogenase, a-ketoglutarate dehydrogenase, succinyl-CoA synthetase, succinate dehydrogenase, fumarase, and malate dehydrogenase. (a) Write a balanced equation for the reaction catalyzed by each enzyme. (b) Name the cofactor(s) required by each enzyme reaction. (c) For each enzyme determine which of the following describes the type of reaction(s) catalyzed: condensation (carbon carbon bond formation); dehydration (loss of water); hydration (addition of water); decarboxylation (loss of CO2), oxidation-reduction; substrate-level phosphorylation; isomerization. (d) Write a balanced net equation for the catabolism of acetyl-CoA to CO2.
