The correct answer is phosphorylation. When an ADP (Adenine Diphosphate) molecule gains a phosphate, it becomes an (Adenine Triphosphate) molecule. This process is called a phosphorylation. Phosphorylation and its counterpart dephosphorylation change many proteins in terms of its functions and activities.
