Final answer:
Adenosine triphosphate (ATP) is a chemical energy molecule that activates muscles in the body.
Step-by-step explanation:
Adenosine triphosphate (ATP)
ATP is a chemical energy molecule that carries out various bodily processes, but one of its primary functions is activating muscles.
ATP is considered the 'energy currency' of cells and is used to provide energy for muscle contraction. When ATP is hydrolyzed (broken down), it releases energy that powers muscle movements.
For example, during exercise, ATP is rapidly resynthesized to meet the energy demands of contracting muscles.
