The first acceptor of electrons from an excited chlorophyll molecule of photosystem II is:

Options

  1. Airon-sulphur protein
  2. Bferredoxin
  3. Cquinone
  4. Dcytochrome.

Correct answer

C. quinone

Step-by-step solution

Electrons from excited chlorophyll molecule of photosystem II are accepted first by Quinone. Photosystem II is a photosynthetic pigment system along with some electron carriers that is located in the appressed part of the grana thylakoids. Photosystem II has chlorophyll a, b and carotenoids. Other components of PS II are phaeophytin, plastoquinone (PQ), cytochrome complex and blue coloured copper containing plastocyanin. Related Theory Photosystem II is a photosynthetic pigment, along with some electron carriers, t
