What type of energy change does hydrolysis of ATP involve in relation to water?

The hydrolysis of ATP primarily involves the consumption of water during the reaction. In this process, one molecule of ATP reacts with water (H2O) to break the high-energy phosphate bond and release energy, resulting in the formation of adenosine diphosphate (ADP) and inorganic phosphate (Pi). This reaction is crucial in biochemical pathways because it provides the necessary energy for various cellular functions.

When ATP is hydrolyzed, the water molecule is used to facilitate the breaking of the phosphate bond, which is a key point here. Essentially, water acts as a reactant in the hydrolysis reaction, underscoring its role in energy metabolism. In contrast, the other provided options do not accurately reflect the nature of the ATP hydrolysis process regarding its interaction with water.
