ATP STRUCTURE AND PRODUCTION
Adenosine triphosphate, or ATP, is the energy currency of cells. A cell
uses ATP to perform almost all of its acvies, including synthesizing proteins,
transporng ions across the cell membranes, and causing organelles and cilia to
move. Cells use the readily available energy supplied by ATP to power its acvies
wherever it is needed.
