Answer:
Exchange reaction.
Step-by-step explanation:
ATP (adenosine triphosphate) is known as the energy currency of the cell. The ATP is used in the body during various metabolic reactions and during the transport of molecules against the concentration gradient.
The ATP molecule undergoes the chemical reaction and the exchange reaction. The phosphate molecule is exchanged during the reaction that makes the ATP active and used to add energy in the cell system of the body.
Thus, the example is exchange reaction.
