Here are the properties of the hydrolysis of ATP:
- Energy output: Hydrolysis of ATP provides 7.3 kcal of energy, which is more than enough to power many cellular reactions.
- Reversibility: Like most chemical reactions, the hydrolysis of ATP to ADP is reversible. The reverse reaction combines ADP + Pi to regenerate ATP from ADP.
- pH: Due to the acid-base properties of ATP, ADP, and inorganic phosphate, the hydrolysis of ATP has the effect of lowering the pH of the reaction medium.
- Stability: ATP is an unstable molecule in unbuffered water, in which it hydrolyzes to ADP and phosphate. It is best stored as an anhydrous salt.
- Exergonic: ATP hydrolysis is an exergonic process, meaning it releases energy.
- Role: ATP hydrolysis is the final link between the energy derived from food or sunlight and useful work such as muscle contraction, the establishment of electrochemical gradients across membranes, and biosynthetic processes necessary to maintain life.
