The last reaction of glycolysis is catalyzed by the enzyme pyruvate kinase. The reaction is shown below Reaction 1 Pyruvate kinase H? Mg²+, K+ H?C OH ADP ATP OH OH Phosphoenolpyruvate Pyruvate i. The AG" of this reaction is -31.4 kJ/mole. Given this information, what is the AG" of hydrolysis of phosphoenolpyruvate ? Phosphoenolpyruvate + H?0 -> pyruvate + Pi AG'°=? ii. Mg²+ is a required cofactor for this reaction. What role does the Mg²+ play? iii. What is the K'eq of the reaction shown above? Does this seem readily reversible under biochemical standard conditions? Why or why not?
