Q. Energy transfer in photosynthesis occurs as
A) Phycoerythrin$\rightarrow$ phycocyanin $\rightarrow$carotenoid $\rightarrow$chlorophyll-a
B) Chlorophyll-b $\rightarrow$carotenoid $\rightarrow$phycoerythrin $\rightarrow$chlorophyll-a
C) Phycocyanin$\rightarrow$phycoerythrin$\rightarrow$ carotenoid$\rightarrow$ chlorophyll-a
D) Chlorophyll-b$\rightarrow$ carotenoid$\rightarrow$ phycocyanin$\rightarrow$ chlorophyll-a
Explanation
Chlorophyll is the principle pigment involved in photosynthesis. Chlorophyll-a is the major pigment involved in trapping light energy and converting it into electrical and chemical energy. Chlorophyll-b molecules also act as accessory pigment. Other accessory pigments are phycoerythrin, phycocyanin, carotenoids, etc. the accessory pigment and reaction centre together from photo system.
