Cytb photosynthesis
WebThe cytochrome b6f complex is an integral membrane protein complex which catalyzes electron transfer from plastoquinol to plastocyanin and pumps protons across the thylakoid membrane. Its turnover rate in chloroplasts can be up to 300 s −1 (reviewed in Hauska et al., 1983; Hope, 1993; Cramer et al., 1994 ). WebPhotosynthesis Photosynthesis and (Aerobic) Respiration These two processes have many things in common. ... From cytb 6 /f, the electrons go to PQ and bring more H+ into the lumen as they move on to PSI again. …

WebFeb 4, 2010 · The phototrophic species of this cluster are characterised by the presence of RCI-type photosystems in their photosynthetic chains, a property which distinguishes them from the two further phyla containing phototrophs, i.e. the Chloroflexaceae and the purple bacteria, which we are inclined to call the orange and purple clades.
WebThe set of wavelengths absorbed by a pigment is its absorption spectrum. In the diagram below, you can see the absorption spectra of three key pigments in photosynthesis: chlorophyll a, chlorophyll b, and β … Cytochrome b is commonly used as a region of mitochondrial DNA for determining phylogenetic relationships between organisms, due to its sequence variability. It is considered to be most useful in determining relationships within families and genera. Comparative studies involving cytochrome b have resulted in new classification schemes and have been used to assign newly described species to a genus as well as to deepen the understanding of evolutionary relationships.
