The steps through which pyruvate from glycolysis is converted into pyruvate dehydrogenase complex are to be explained. Concept introduction:  The breakdown of a glucose molecule to produce ATP, NADH, and pyruvate molecules is called glycolysis.  The pyruvate is the initial reacting substrate for the citric acid cycle that goes through several reactions in the presence of the enzyme pyruvate dehydrogenase complex to give acetyl-CoA.  The pyruvate dehydrogenase complex is a set of five enzymes, namely, pyruvate dehydrogenase, hydro lipoyl transacetylase, dihydrolipoyl dehydrogenase, pyruvate dehydrogenase kinase, and pyruvate dehydrogenase phosphatase.
