What happens when ATP is converted to ADP? Energy is stored in bonds. Energy is released from bonds. Energy remains in the same. The cell dies.

Energy stored in food can be used by cells to add a phosphate group to ADP to make ATP. This cycling of ATP to ADP occurs in a metabolic process called cellular respiration. phosphate group breaks, and energy is released. ATP becomes ADP, and the cycle of storing and releasing energy continues until the cell dies.
