(a) Interpretation : Enzymes needed to get the net formation of oxaloacetate from acetyl Co-A. Concept introduction : The citric acid cycle is a catabolic process. It is a series of chemical reactions in which the stored energy of the body is released by the oxidation of acetyl-Coenzyme A. Pyruvate dehydrogenase enzyme complex is required for the linking of glycolysis and TCA. It helps in the conversion of pyruvate into Acetyl CoA. Acetyl CoA then enters into the series of the citric acid cycle.
