Question

Quizplus · Accepted Answer

ATP (adenosine triphosphate) is the primary source of direct energy for cells. It is the "energy currency" used by cells to perform various functions, including muscle contraction, cell division, and active transport of molecules across cell membranes. Glucose and glycogen can be broken down to produce ATP through cellular respiration, but ATP itself is the immediate source of energy used by cells. Fat can also be broken down to produce ATP, but it is not the primary source of direct energy for cells.
