How does atp power a chemical reaction? a. molecules of atp are converted back to adp, releasing the energy stored in their phosphate bonds. b. each molecule of atp breaks down into three phosphate molecules, releasing energy from phosphate bonds. c. atp is used to break the bonds of glucose molecules, releasing energy for chemical reactions. d. molecules of adp are converted to atp, releasing energy as phosphate groups are added.

Your answer is A- Molecules of ATP are converted back to ADP, releasing the energy stored in their phosphate bonds.
