u know bond-breaking absorbs energy, but why the hydrolysis of ADP, which is bond breaking, releases energy?

Theres a number of ways to think about but to put it simply :
your mitochondria uses energy it gets from allowing protons to flow with their concentration to force phosphate groups onto ADP molecules. These bonds do not want to be made, so they have energy because it took energy to create them. This is potential energy, like when you lift something heavy. This energy can be used in other places in the cell by breaking this bond, releasing the energy used to form it. ( ATP molecule that break off phosphate group can also form a bond with a molecule, which releases energy. This energy lets the cell do stuff.)
