Question

Quizplus · Accepted Answer

ATP releases energy when one phosphate group leaves and becomes ADP (adenosine diphosphate). This energy can be used by cells for various processes such as muscle contraction and cellular metabolism. ATP contains three phosphate groups, not five. The bond between the second and third phosphate groups is actually a high-energy bond, making it less stable than other phosphate bonds in the molecule. ATP also does not contain glucose, which is a different type of molecule.
