Detailed Solution

In light reaction, plastoquinone facilitates the transfer of electrons from PS II to cytb6f complex.From Cyt f , the electrons are picked up by a copper-binding protein, plastocyanin (PC) to P700Ferrodoxin is used to tranfer electron from PS -I to NADP+. Ferredoxin in turn is used to reduce NADP+, a reaction mediated by the enzyme ferredoxin-NADP+-oxidoreductase.
