Question

The function of light in photosynthesis is

• A. photolysis of water
• B. assimilation of carbon dioxide
• C. production of organic food
• D. activation of enzymes

Answer 1

The correct option is A photolysis of water

The process of photosynthesis occurs when green plants use the energy of light to convert carbon dioxide (CO2) and water (H2O) into carbohydrates. Light energy is absorbed by chlorophyll, a photosynthetic pigment of the plant. This process is to change the energy in sunlight into the energy in sugar, the end product of photosynthesis. Photosynthesis of water resulting H+ion for the reduction of NADPH2.

So, the correct option is, 'photolysis of water'.
