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 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.

Web15 mrt. 2024 · The non-cyclic flow of electrons from PS-II through quinone, cytochrome b6f complex, and plastocyanin to NADPH through PS-I is called the Z scheme of light reaction. PS-I and PS-II are both included in the Z scheme reaction. Photosystem I is a protein complex that uses the light energy photon to accelerate the transfer of electrons. WebThe currently accepted scheme for photosynthetic electron flow from water to ferredoxin (and subsequently to NADP), known as the Z scheme, envisions a linear electron flow that requires two photosystems joined by several electron carriers.
