The hydrolysis of ATP to ADP has a △G°' of -30 kJ/mol. If in an E. coli cell the concentrations of ATP, ADP and inorganic phosphate are 7.90 mM, 1.04 mM and 7.9 mM, respectively, which statement is true about the hydrolysis of ATP in the cell? (Assume a temperature of 298 K. R = 8.315 J/K-mol) A. The formation of ATP from ADP is occurring more rapidly than the hydrolysis. B. The hydrolysis is being allosterically controlled. C. Hydrolysis can proceed spontaneously. D. The hydrolysis is at equilibrium.
