WebApr 11, 2024 · The thylakoid membrane is covered with cyt B6F. Two H+ are released into the lumen, and two electrons are transferred to Cyt B6f once PQH2 reaches there. Cytochrome b6f → Phycocyanin: The next protein receives the electrons, which are now transmitted once again one at a time. The potential of cytot b6f is greater than that of … WebIn this study we have generated transgenic Arabidopsis plants over-expressing the Rieske FeS protein (PetC), a component of the cytochrome b6f (cyt b6f) complex. Increasing the levels of this protein, resulted in the concomitant increase in the levels of cyt f (PetA) and cyt b6 (PetB), core proteins of the cyt b6f complex.
Web2. Reduced ferredoxin, unable to reduce NADP+ returns the electron to PS I via cytochrome b 6, plastoquinone (PQ), cytochrome-f and plastocyanin. 3. The electron transport is called cyclic because the electron emitted from PS I returns back to PS I passing through several intermediate carriers. Hence, the correct answer is 'Cyt.b6'. WebMar 1, 1994 · We show that the rates of synthesis of cyt b6 and suIV are independent of the presence of the other subunits of the complex but that their stabilization in the thylakoid membranes is a concerted process, with a marked dependence of suIV stability on the presence of cyt b6. In contrast, mature cyt f was stable in the absence of either suIV or ...
