      • The energy generated by the hydrogen ion stream allows ATP synthase to attach a third phosphate to ADP, which forms a molecule of ATP in a process called photophosphorylation.

  1. The hydrogen ions play critical roles in the remainder of the light-dependent reactions. Figure \(\PageIndex{1}\): Light energy is absorbed by a chlorophyll molecule and is passed along a pathway to other chlorophyll molecules.

  2. In non-cyclic photophosphorylation, cytochrome b6f uses the energy of electrons from PSII to pump hydrogen ions from the lumen to the stroma; this energy allows ATP synthase to attach a third phosphate group to ADP, which forms ATP.

  8. The energy travels to the reaction center that contains chlorophyll a to the electron transport chain, which pumps hydrogen ions into the thylakoid interior. This action builds up a high concentration of ions.
