A molecule of ATP contains adenine, ribose, and three phosphate groups. The bond between the last two phosphates is easily broken, resulting in a molecule of ADP and one phosphate group. If the bond between the second and third phosphate groups were more stable, what would be the most likely consequence? The bond between the first and second phosphates would have to be broken to produce energy. More energy would be required to break the bond, so the net energy produced would be less. Once the bond between the phosphate groups is broken the net energy released would increase. The reaction that breaks the bond would begin to take place at a higher temperature.
