Explanation

ATP (Adenosine triphosphate) functions as the main energy carrier in cells. During metabolic reactions, not all energy is released immediately; instead, some is stored in the high-energy phosphate bonds of ATP. When the cell needs energy, these bonds are broken, releasing energy to power various cellular activities. Therefore, ATP is recognized as the cell's energy currency.
