The equilibrium constant for the reaction of ADPβS and 1,3-diphosphoglycerate to give ATPβS and 3-phosphoglycerate is 400.
a. What is ΔG°´ for this reaction?
Assume equal starting concentrations of ADPβS and 1,3-diphosphoglycerate to answer the following:
b. What percent of each reactant will remain at equilibrium?
c. What is the free energy change for the reaction after 10% of the reactants have been converted to products?
d. What is the free energy change for the reaction after 50% of the reactants have been converted to products?
e. Plot ΔG´ as a function of the ratio of [ATPβS]/[ ADPβS] for the range 1/100 to 100/1. The plot may be done either manually or with a graphing program, and should be fully labeled.
