WebAug 10, 2024 · The cytochrome b6f and ATP synthase complexes abundance, depending on the growth light intensity, are correlated with the rate of electron transport . Mu et al. [ 72 ] showed that plants invest more N to the bioenergetics pool to support electron transport and photophosphorylation, preferentially reduce PEPC, and use PPDK, Rubisco, and light ... WebThe restriction at the Cyt b6f complex can be gradually relieved with continued illumination. This study provides insights into how photosynthetic electron transport responds to a marked reduction in availability of downstream electron acceptors and the protective mechanisms involved.

WebApr 10, 2024 · The electrons transfer from pheophytin to plastoquinone, which takes the 2 electrons from Pheophytin, and two hydrogen Ions from the stroma and forms PQH 2, which later is broken into PQ, the 2 electrons are released to Cytochrome b6f complex and the two hydrogen ions are left out into thylakoid lumen. The electrons then travel through the … WebDec 14, 2024 · The cofactors and quinone binding pockets involved in electron transfer are found in the b 6 f core subunits which resemble the cytochrome bc 1 complex of the respiratory chain. The structure–function similarities suggest that the hydrophilic domain of PETC subunit would move toward PetA subunit in transferring the electrons from Rieske … Webb6f complex is not involved in cyanobacterial state transitions, is based entirely on our own results presented in the article and is not altered by this correction. chi\u0027s sweet home 4
