Free Energy Calculations - Step-by-step Answers

1. If the equilibrium concentrations of ATP = 1x10^-7 M, ADP = 0.165 M and P_i = 0.1 M, what is the equilibrium constant and DG^o' for the hydrolysis of ATP at 37^oC? (step-by step answer).
2. In a typical cell at 37^oC the concentration of ATP = 8 x 10^-3 M, ADP = 1 x 10^-3 M, and P_i = 8 x 10^-3 M. What is the actual free energy change (DG') for ATP hydrolysis under these conditions? ( step-by step answer).
