Question

A specific function of light in the process of photosynthesis is

• A. Reduction of $C{O}_2$
• B. Activate other molecules
• C. Split water molecules
• D. None of the above.

Answer 1

The correct option is C Split water molecules

Photolysis of water means splitting of water in the presence of light to get $H^{+}$ nascent oxygen and electron that compensate the loss of an electron from PS II during Z scheme and oxygen is released a the by-product with $H^{+}$ that acts as a proton and collects in the stroma.

So the correct option is 'Split water molecules'.
