We have seen all term that cells use the hydrolysis of high energy phosphate from ATP to make metabolic reactions thermodynamically favorable. Whereas most enzymes that utilize ATP hydrolyze between the b and g phosphates (yielding ADP + Pi), some enzymes hydrolyze ATP between the a and b phosphates (yielding AMP and PPi). ∆G°’ of phosphate hydrolysis is -31 kJ/mol for ATP + H2O --> ADP + Pi, and ∆G°’ of phosphate hydrolysis is -46.5 kJ/mol for ATP + H2O...
