<P> Photosystem II is located mostly in the grana thylakoids , whereas photosystem I and ATP synthase are mostly located in the stroma thylakoids and the outer layers of grana . The cytochrome b6f complex is distributed evenly throughout thylakoid membranes . Due to the separate location of the two photosystems in the thylakoid membrane system , mobile electron carriers are required to shuttle electrons between them . These carriers are plastoquinone and plastocyanin . Plastoquinone shuttles electrons from photosystem II to the cytochrome b6f complex , whereas plastocyanin carries electrons from the cytochrome b6f complex to photosystem I . </P>
