(1) The transport of two electrons and two protons, by the diffusion of plastoquinone, from the stroma side of P2 to the luen side of the cytochrome complex and (2) the transfer of electrons within the cytochrome complex to a different molecule of plastoquinone, which results in additional protons being picked up from the stroma and subsequently released into the lumen.
