Brief Overview: Glycolysis

Brief overview: Glycolysis

Pyruvate Dehydrogenase PDH Pyruvate dehydrogenase is the enzyme that converts pyruvate to acetyl-CoA, as well as reduce NAD+ to NADH. Pyruvate is decarboxylated by PDH, releasing a CO 2 molecule, and the remaining two-carbon unit (acetate) is combined with CoA to give Acetyl CoA. Rate limiting enzyme, determines the rates of glycolysis, lactate production, and carbohydrate supply for mitochondrial oxidation.
