First ATP bonds are broken, so that we are left with ADP + P i, which releases energy; however, most of the energy stays with the broken-off phosphate, which we can then bond to the molecule that needs the energy. The process of adding a phosphate is phosphorylation. 2. The ADP molecule can then ...
