WebQuestion: Briefly describe the organization and function of a) photosystems II (p680) and I (p700), b) cytb6f complex and c) ATPase in the thylakoid membranes of plant chloroplasts. Outline how the flow of electrons and the flow of protons occurs in this system of complexes. How does the system involving cyclic phosphorylation differ from the PSII/cytb6f/PSI … WebCytB6F Can undergo redox chemistry; reduction accompanied by production of a H+ to help generate the proton gradient needed by ATP synthase; links PSI and PSII- Oxygen evolving complex Part of Photosystem II, contains special Mn and Tyr radical; responsible for replenishing p680* electron using water Fructose 2,6-bisphosphate
