Cytb6f complex
WebCyanobacteria are photosynthetic microbes with highly differentiated membrane systems. These organisms contain an outer membrane, plasma membrane, and an internal system of thylakoid membranes... WebThe cytochrome b6f complex (Cyt b6f), which is reduced from the reducing side of PS II by plastoquinone (PQ) and gives up its electrons to plastocyanin, is found between grana disks and the stromal thylakoid.

WebWe conducted western blot experiments to assess changes in the accumulation of two photosynthetic complexes (PSII, and Cytb6f complex) and the ATP synthase in tobacco plants over two days of acclimation to low temperature. Surprisingly, the concentration of proteins within the chloroplast varied negligibly compared to controls. 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 …
WebMar 7, 2024 · Under steady-state continuous illumination, the ECS signal stems from transmembrane potential generation by PSII, the cytb6f complex, and PSI and from transmembrane potential dissipation by the ATP synthase CF 0-F 1.
