7.2 explain that the biologically important part of the molecule contains three phosphate groups linked by high energy phosphodiester bonds
explain that the biologically important part of the molecule contains three phosphate groups linked by high-energy phosphodiester bonds
- The energy used by cells is stored in the bonds between the phosphate groups in ATP. The hydrolysis (splitting) of ATP to give ADP and Pi yields 30.5 kJ of energy per mole of ATP. This large amount of free energy comes from breaking one phosphodiester bond.
