Animal Nutrition Lecture #6 March 19, 2008 Regulation of Glycolysis Three Glycolysis enzymes catalyze spontaneous reactions: Hexokinase, Phosphofructokinase, Pyruvate Kinase Control of these enzymes determines the rate of the Glycolysis pathway The matrix contains Pyruvate Dehydrogenase, enzymes of Krebs Cycle, and other pathways Inner membrane infoldings, called cristae, contain constituents of the respiratory chain & ATP Synthase. The inner membrane is the major permeability barrier. It contains various transport catalysts, including a carrier protein that allows pyruvate to enter the matrix. Pyruvate Dehydrogenase, catalyzes oxidative decarboxylation of pyruvate, to form acetyl-CoA. In the overall reaction catalyzed by the Pyruvate Dehydrogenase complex, the acetic acid that is generated is transferred to coenzyme A, and NAD + is the final electron acceptor. The Kreb’s Cycle
