In photosystem-I, the first electron acceptor is:

Options

  1. Aan iron-sulphur protein
  2. Bferredoxin
  3. Ccytochrome
  4. Dplastocyanin

Correct answer

A. an iron-sulphur protein

Step-by-step solution

In photosystem I, the primary electron acceptor is probably a Fe-S protein. The reduced primary acceptor transfers the electrons to the secondary electron acceptor P ₄₃₀ . The reduced P ₄₃₀ passes its electrons to ferredoxin ( Fd ) present at the outer surface of the thylakoid membrane. Related Theory In light reaction of photosynthesis two types of photosystems are involved. PS-I consists of plenty of chlorophyll- a and very less quantity of chlorophyll-b. These pigments absorb light energy and transfer it to the
