Z‐Scheme of Photosynthesis - CliffsNotes
WebThis whole scheme of transfer of electrons, starting from the PS II, uphill to the acceptor, down the electron transport chain to PS I, excitation of electrons, transfer to another acceptor, and finally down hill to NADP+ reducing it to NADPH + H+ is called the Z scheme, due to its characterstic shape (Figure 13.5). Web4 sep. 2024 · The electron transport chain of photosynthesis is often put in a diagram called the z-scheme, because the redox diagram from P680 to P700 resembles the letter Z. to NADPH. Activities of the electron transport chain, especially from cytochrome b6f, lead to pumping of protons from the stroma to the lumen. chinaledger联盟

WebElectrons will jump from p680 to a primary electron acceptor, which will pass them to an electron transport chain(indicated by the orange arrow at “b”). The electron transport chain (ETC) is a series of enzymes embedded in the thylakoid membrane, each more electronegative than the previous one. Webpathway is also called as the ‘Z-scheme of photosynthesis’ because the redox diagram from P 680 to P 700 looks like a big alphabet ‘Z’. In this scheme of electron transport, the electron ejected from PSII did not return to its place of origin, instead it was passed on to PSI. Similarly, the WebZ-scheme is a diagrammatic representation of the electron flow in non-cyclic phosphorylation, showing the change in energy potential of the electrons.
