The free energy change of ATP hydrolysis at 25 C is -32.2 kJ mol-1. The free
energy change for hydrolysis of α-glycerophosphate to glycerol is -8.2 kJ mol-1 at
25 C. Using the above information, the free energy change for the formation of
α-glycerophosphate from glycerol and ATP is ________ kJ mol-1 (Answer in
integer).
