WebIn the presence of coenzyme A (CoA), PDH oxidizes pyruvate to acetyl coenzyme A (acetyl CoA) which is the starting material for the citric acid cycle; α-ketoglutarate dehydrogenase catalyzes the oxidation of α-ketoglutarate to form succinyl CoA, which is a key intermediate in the citric acid cycle; and BCKDC catalyzes the oxidation of branched … WebMost acetyl-CoA is utilized in mitochondria via the tricarboxylic acid (Krebs) cycle. Citrate synthase (EC4.1.3.7) joins acetyl CoA to oxaloacetate. The citrate from this reaction can then be metabolized further providing FADH, NADH, and succinate for oxidative phosphorylation and ATP or GTP from succinyl CoA.
