WebWhy does the hydrolysis of ATP into ADP and Pi have a negative G (is thermodynamically favorable)? If energy has to be used to break bonds (like the one holding the phosphate group on the rest of the molecule), why does ATP hydrolysis release energy that can be used to power other endergonic reactions? WebEnergy Output in ATP Hydrolysis. The hydrolysis of 1M of ATP into ADP and inorganic phosphate, releases −7.3 kcal/mol of energy. The energy released in the living cell is almost double the value in standard conditions, it is equal to −14 kcal/mol. The hydrolysis of ATP into AMP and pyrophosphate (PPi) releases −10.9 kcal/mol of energy.
