What is ADP phosphorylation? What respectively are photophosphorylation and oxidative phosphorylation?

ADP phosphorylation is the addition of one inorganic phosphate in the molecule of adenosine diphosphate therefore creating ATP (adenosine triphosphate) and incorporating energy. The phosphorylation is oxidative when the energy incorporated comes from the breaking of organic molecules having oxygen as reagent, as in aerobic cellular respiration. The reaction is known as photophosphorylation when the energy source is light, as in photosynthesis.

The energy incorporated into ATP is disposable (liberated) to other cellular reactions when ATP hydrolyzes and ADP is produced again.
