Fluoride inhibits enolase by reaction with Mg+2 to form the precipitate, MgFPO3. What metabolite intermediate will accumulate when F is added to cell- free extracts capable of glycolysis? Describe the reaction mechanisms of aldolase (Schiff base formation, electron sink), triose-P isomerase or P-glucose-isomerase (enediol intermediate) and glyceraldehyde 3-P dehydrogenase (thioester formation, covalent enzyme intermediate in energy coupling). What is the net yield of ATP per glucose molecule by the glycolytic pathway? Write out the reactions of the glycolytic pathway from glucose to lactate using structural formulas for all intermediates. Learn the names of these intermediates and the enzymes that catalyze the reactions. Describe 2 anaerobic catabolic fates of pyruvate? Why is the the cell's ability to regenerate NAD+ critical to glycolysis? In reactions not requiring structures, describe the reactions that allow galactose, fructose and mannose carbons to be metabolized via glycolysis. Specify the organs where these reactions are prevalent.
