Final answer:
ATP is chemical energy that all cells use.
Step-by-step explanation:
True, ATP (adenosine triphosphate) is indeed chemical energy that all cells use. ATP is known as the energy currency of the cell because it stores and releases energy for various cellular activities. It is generated during cellular respiration, where energy is harvested from nutrients. Cells use ATP for processes like muscle contraction, active transport, and synthesis of macromolecules.
