Question

what are the functions of H2O and chlorophyll in the process of photosynthesis

Answer 1

Role of water in photosynthesis:

• The electrons being transferred in the photo-phosphorylation reactions are generated by the splitting of water.

• The light-dependent splitting of water is called photolysis
  2H₂O → 4H⁺ + O₂ + 4e^−

• Electrons formed are used for replacing the electrons lost from P680.

• Oxygen is liberated as a byproduct of photosynthesis.

Role of chlorophyll in photosynthesis:

Chlorophyll has the ability to absorb light energy which is then converted into chemical energy. This chemical energy is used in the formation of carbohydrates.
