Answer: by the addition of one phosphate group.

Explanation: ADP (adenosine diphosphate) gains an inorganic phosphate (Pi) to become ATP (adenosine triphosphate). This phosphorylation requires energy (e.g., from oxidative phosphorylation by ATP synthase, substrate-level phosphorylation in glycolysis, or photophosphorylation in chloroplasts).
