3. Phosphorylation of ADP (The payoff!)
The hydrogen ions (H+), on the side of the membrane where most concentrated, will eventually flow back across the membrane, down the proton gradient, through an enzyme called ATP synthase.
As each H+ moves back across the membrane, the enzyme ATP synthase phosphorylates (adds a phosphate to) adenosine diphosphate (ADP) to make the high energy molecule ATP, which can be used for many different energy-requiring reactions throughout the cell.
