The properties and functions of water
The ATP hydrolysis reaction is reversible. The reverse is a condensation reaction and it is catalysed by ATP synthase. The reaction combines ADP and inorganic phosphate to reform ATP.
ATP can be hydrolysed to produce adenosine diphosphate (ADP) and an inorganic phosphate.
Adenosine triphosphate (ATP) is a universal energy supplier for all living organisms. It is a small and soluble organic molecule that is formed from adenine, ribose and three phosphate ions.
