NEET 2006 Biology question

In photosystem-I, the first electron acceptor is-

(1)Ferredoxin
(2)Cytochrome
(3)Plastocyanin
(4)An iron sulphur proteinCorrect

Answer: (4)

Solution

In PS I the reaction-centre chlorophyll P700 absorbs light and, on excitation, passes the electron first to the primary acceptor A0 (a chlorophyll) and then to A1 (phylloquinone) and to iron-sulphur centres (Fe-S proteins), from which it goes to ferredoxin. Among the options
