The G for ATP hydrolysis is 230.5 kJ mol 1 (27.3 kcal mol 1 ). In the

The ΔG°´ for ATP hydrolysis is 230.5 kJ mol^–1 (27.3 kcal mol^–1). In the red blood cell at 37°C (310 K) the concentrations of ATP, ADP, and phosphate are 2.25, 0.25, and 1.65 mM, respectively. Show that these are not the equilibrium concentrations, and calculate the actual ΔG´ under these conditions. (2.3RT at 37°C is 5.93 kJ mol^–1 [1.42 kcal mol^–1].)
