Question

The role of phycobilins in photosynthesis is to

• A. Absorb and transfer energy to chlorophyll
• B. Donate electrons to electron transport system
• C. Fix carbon dioxide
• D. Carry hydrogen or electrons

Answer 1

Answer: (A)

Absorb and transfer energy to chlorophyll

Phycobilins function as light-harvesting pigments in most species of cyanobacteria and red algae. They act as light-absorbing pigments for photosynthesis and are capable of absorbing light in the green and orange region of visible light where chlorophyll absorbs poorly.

Hence, the correct answer is 'Absorb and transfer energy to chlorophyll'.
