ATP + H2O à ADP + Pi (-7.3 kcal/mol)
A. Calculate delta G for ATP hydrolysis when the concentration of ATP, ADP, Pi are all equal to 1mM. What is delta G when the concentration of ATP, ADP, and Pi when the concentration of ATP, ADP, and Pi are all equal to 2M?
B. What will delta G equal when the hydrolysis reaction reaches equilibrium? At [Pi] = 5mM, what will be the ratio of [ATP] to [ADP] at equilibrium?
C. Show that, at a constant [Pi], delta G decreases by 1.4 kcal/mol for every 10-fold increase in the ration of [ATP] to [ADP], regardless of the value of delta G^0.
