Which group is common in cyclic and non-cyclic phosphorylation?

Explanation

The cytochrome b6f complex is a protein complex that facilitates the transfer of electrons between plastoquinone and plastocyanin, ultimately creating a proton gradient across the thylakoid membrane.Electrons from plastoquinone are transferred through the cytochrome b6f complex to plastocyanin. As electrons move through this complex, protons are pumped across the thylakoid membrane from the stroma to the thylakoid lumen. Plastocyanin is a small protein that acts as an electron carrier in the thylakoid membrane. Plastocyanin receives electrons from the cytochrome b6f complex and transfers them to photosystem I (PSI). Ferredoxin is a small iron-sulfur protein that acts as an electron carrier in photosynthetic organisms.Ferredoxin receives electrons from PSI and transfers them to ferredoxin-NADP+ reductase, which catalyzes the reduction of NADP+ to NADPH. This step is crucial for the production of NADPH, which is used in the Calvin cycle for carbon fixation.
