Question

In PS I, the carrier that picks up electrons from $P_{700}$ is

• A. Fe protein
• B. Fe-S protein
• C. Fe-Cu protein
• D. Fe-Mg protein

Answer 1

The correct option is B Fe-S protein

A photosystem is composed of chlorophyll 'a' molecule which can absorb the wavelength of 700 nm. The chlorophyll a molecule acts as a reaction centre. PS-I is involved in a non-cyclic type of photophosphorylation where there is a chain of electron carriers and acceptors that transmits the electron from one to another. The primary electron acceptor is the ferredoxin molecule which is composed of Fe-S protein

So, the correct option is Fe-S protein'
