Energy transfer in photosynthesis occurs as
Phycoerythrin Phycocyanin Carotenoid Chlorophyll a
Chlorophyll b Carotenoid Phycoerythrin Chlorophyll a
Phycocyanin Phycoerythrin Carotenoid Chlorophyll a
Chlorophyll b Carotenoid Phycocyanin Chlorophyll a
A.
Phycoerythrin Phycocyanin Carotenoid Chlorophyll a
Chlorophyll is the principal 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 acts as accessory pigment.
Other accessory pigments are phycoerythrin, phycocyanin, carotenoids etc. The accessory pigment and reaction centre together form photo-system.
In photosynthesis what occurs in PS-II?
It takes longer wavelength of light and e- from H2O
It takes shorter wavelength of light and e- from H2O
It takes longer wavelength of light and e- from NADP
It takes shorter wavelength of light and e- from NADP
