Energy transfer in photosynthesis occurs as
Options
- APhycoerythrin Phycocyanin Carotenoid Chlorophyll a
- BChlorophyll b Carotenoid Phycoerythrin Chlorophyll a
- CPhycocyanin Phycoerythrin Carotenoid Chlorophyll a
- DChlorophyll b Carotenoid Phycocyanin Chlorophyll a
Correct answer
C. Phycocyanin Phycoerythrin Carotenoid Chlorophyll a
Step-by-step solution
Photosynthetic pigments mainly occur on thylakoid membranes. These are major pigments like chlorophylls and accessory pigments like phycoerythrin, phycocyanin, and carotenoids. The accessory pigments absorb light energy of various wavelength and get excited and transfer the energy to chlorophyll-a molecule through electron spin resonance. Order of energy transfer in photosynthesis occur as phycocyanin followed by phycoerythrin followed by carotenoids and finally to chlorophylls.
