Question

Which of the following is the correct sequence of the process of photosynthesis?

• A. Splitting of water to H2 and O2 → Absorption of light by Chlorophyll → Reduction of CO2 → Carbohydrate formation
• B. Splitting of water to H2 and O2 → Reduction of CO2 → Absorption of light by Chlorophyll → Carbohydrate formation
• C. Absorption of light by Chlorophyll → Splitting of water to H2 and O2 → Reduction of CO2 → Carbohydrate formation
• D. Absorption of light by Chlorophyll → Reduction of CO2 → Splitting of water to H2 and O2 → Carbohydrate formation

Answer 1

The correct option is C Absorption of light by Chlorophyll → Splitting of water to H2 and O2 → Reduction of CO2 → Carbohydrate formation

• The following events occur during photosynthesis:
  • Absorption of light energy by chlorophyll.
  • Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.
  • Reduction of carbon dioxide to carbohydrates.
