Which of the following is the correct sequence of events during photosynthesis in plants?
- A.Absorption of light energy -> Reduction of carbon dioxide to carbohydrates -> Conversion of light energy to chemical energy
- B.Absorption of light energy -> Conversion of light energy to chemical energy -> Splitting of water molecules into hydrogen and oxygen -> Reduction of carbon dioxide to carbohydratesCorrect answer
- C.Splitting of water molecules -> Absorption of light energy -> Reduction of carbon dioxide -> Conversion of energy
- D.Reduction of carbon dioxide -> Absorption of light energy -> Splitting of water -> Conversion of chemical energy
Solution
The events in photosynthesis occur in a specific order: first, chlorophyll absorbs light energy; second, this light energy is converted into chemical energy and water molecules are split into hydrogen and oxygen; third, carbon dioxide is reduced to carbohydrates.
