NEET Botany Light Reaction MCQ Question
In the light reaction of photosynthesis, how does the presence of accessory pigments like xanthophylls and carotenoids enhance photosynthesis efficiency?
By expanding the range of light wavelengths absorbed.
By increasing the amount of CO2 fixed in the Calvin cycle.
By directly converting light energy into ATP.
By reducing the oxygen released during photolysis.
Correct Answer
Detailed Explanation
Accessory pigments like xanthophylls and carotenoids absorb light at different wavelengths than chlorophyll a, allowing plants to utilize a broader spectrum of light for photosynthesis, thereby increasing efficiency.
