Answer:
The reaction that converts a lower-energy molecule into a higher-energy molecule is ADP + P + energy.
Explanation:
ATP is the molecule that provides energy to the cell. It possesses three phosphate groups, each of which is bound by high-energy bonds and the separation of a phosphate by hydrolysis of ATP is strongly exergonic. The energy released is used by the cell to perform its functions.
<u>In order to form an ATP molecule, ADP is required to bind to a phosphate group, a process that requires energy </u>to establish the P-O-P bond, so the reaction, which is reversible, would be:
<em> ATP + H₂O ⇄ ADP + Pi + ↑energy </em>
This is what allows to convert a lower-energy molecule into a higher-energy molecule and permits an ATP molecule to become the energy exchanger of living organisms.
