Make a list of everything that comes to mind.Understanding the Oxidation of Glucose and Its Products in the TCA Cycle Glycolysis, the pyruvate dehydrogenase reaction, and the TCA cycle result in complete oxidation of a molecule of glucose to CO2. Review the calculation of oxidation numbers for individual atoms in any molecule, and then calculate the oxidation numbers of the carbons of glucose, pyruvate, the acetyl carbons of acetyl-CoA. and the metabolites of the TCA cycle to convince yourself that complete oxidation of glucose involves removal of 24 electrons and that each acetyl-CoA through the TCA cycle gives up 8 electrons.Effects of Changing Metabolite Concentrations on Glycolysis In an erythrocyte undergoing glycolysis what would be the effect of a sudden increase in the concentration of a.
