Exam 6: Basic Concepts of Enzyme Action

The ΔG°′ for the hydrolysis of ATP to ADP + P_i is approximately –31kJ/mole. Calculate the equilibrium constant for this reaction (R = 8.314J/°mole) at the cellular temperature of 37°C. If the cellular concentrations of ATP, ADP, and Pi are 8, 1, and 8 mM, respectively, is the above reaction at equilibrium in the cell?
