Vedclass · Answer

(D) In the $Z$-scheme of light reaction,electrons are excited by light energy,which represents an uphill movement in terms of redox potential (from a more positive to a more negative potential). Subsequently,these electrons pass through an electron transport chain,which is a downhill movement in terms of redox potential (from a more negative to a more positive potential). Therefore,the movement involves both uphill and downhill processes on the redox potential scale.
