H+ gradient is used to make ATP via ATP synthase (chemiosmosis) The cytochrome b6f complex (plastoquinol—plastocyanin reductase; EC 1.10.99.1) is an enzyme found in the thylakoid membrane in chloroplasts of plants, cyanobacteria, and green algae, that catalyzes the transfer of electrons from plastoquinol to plastocyanin. The reaction is analogous to the … See more The cytochrome b6f complex is a dimer, with each monomer composed of eight subunits.
