Question

Short /Long answer type question.
Trace the non-cyclic electron pathway (Z-scheme), naming and explaining all the events that occur as the electrons move from water to $$NADP^+$$


Solution

A route of electron flow during the light reactions of photosynthesis that involves both photosystems and produces ATP, NADPH, and oxygen. The neet electron flow is from water to NADP+.
The following are the steps in which it occurs:
    • Firstly the light from the sun strikes the PS II system in which it results in splitting of the water molecule by the use of 2 photons.
    • Then due to the above reaction 2 electron is generated which is absorbed by the reaction center of PS II.
    • Then these electron is passed to the primary acceptor which then pass it to the cytochrome complex where one ADP is used and ATP  is released.
    • Then it is passed to the PS I reaction center and it’s is then passed to ferredoxin.
    • In this, the enzyme NADP reductase is acted on the NADP$$^+$$ and proton which result in the release of NADPH.
