The last step of glycolysis converts phosphoenolpyruvate to pyruvate. phosphoenolpyruvate + ADP " pyruvate + ATP A G = -33 kJ/mol (-7.5 kcal/mol) The AG" of the reverse reaction is +31 kJ/mol (+7.5 kcal/mol). Instead of reversing the pyruvate kinase reaction, the step is bypassed in gluconeogenesis. Several steps for the conversion of pyruvate to phosphoenolpyruvate via gluconeogenesis are given. Place the steps in the correct order. You will not place all of the steps. First step
