e. The AG" = 0.4 kcal/mol of this reaction is near zero, indicating that this reaction is readily reversible, especially in the presence of a catalyst. The reversible isomerization of G6P to F6P catalyzed by this enzyme enables it to participate in the reaction in both glycolytic and gluconeogenic pathways. For this step, AG' can be held near zero or it can be shifted upward to ~ 6 kcal/mol. i. Why does the cell sometimes match the AG' with AG" for this step? How might this facilitate regulation of glycolysis? ii. What is achieved by moving AG' upward to 6 kcal/mol? By how much would the cell have to change the [F6P] and [G6P] to achieve this goal? iii. What is the general term for the value that is modified by the cell?
