WebThese bonds are “high-energy” because the products of such bond breaking—adenosine diphosphate (ADP) and one inorganic phosphate group (P i)—have considerably lower free energy than the reactants: ATP and a water molecule. Because this reaction takes place using a water molecule, it is a hydrolysis reaction. WebWhat happens during ATP hydrolysis quizlet? Bonds are broken by hydrolysis. When the terminal phosphate bond is broken by the addition of a water molecule, a molecule of inorganic phosphate leaves the ATP, which becomes adenosine diphosphate (ADP). This reaction is exergonic and releases energy.
