Use the free-energy values given below to predict whether the conversionof creatine phosphate to creatine will provide enough energy to phosphorylate ADP. Determine the net reaction and then calculate the overall ÎG⁰'. Is net reaction spontaneous?

Creatine Phosphate + H20 -> Creatine + Pi

ÎG⁰'= -43.1 kJ/mol

ADP + Pi -> ATP + H2O

ÎG⁰'= 30.5 kJ/mol
