Question

Photo-oxidation or photolysis of water (in photosynthesis) occurs in association of

• A. Cytochrome $b_6$f
• B. Plastocyanin
• C. PS II
• D. PS I

Answer 1

The correct option is C PS II

Photolysis of water is carried out to fulfill the need of electrons that are given by photosystem II to photosystem I in the Z scheme. The splitting of water is associated with PSII in which water is split into H${}^{+}$, [O] and electrons and this also creates oxygen, one of the net product of photosynthesis.

So, the correct option is 'PS II'.
