WebApr 9, 2024 · The reason that these bonds are considered “high-energy” is 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 with the use of a water molecule, it is … WebThe amount of energy needed to break the bond is called the bond energy. Lots of heat and/or light energy is released when very strong bonds form, because much of the chemical energy is converted to heat and/or light energy.
