Question
In Photosystem-I the first rlectron acceptor is
Options
A.cytochrome
B.plastocyanin
C.an iron-sulphur protein
D.ferredoxin
Solution
In Photosystem-I the primary electron acceptor is peobably a Fe-S protein. The reduced primary acceptor transfers the electrons to secondary elecrron acceptron transferis as follows :
The reduced P430 passes its electrons to ferredoxin (Fd) present at outer surface of thylakoid membrane.
