1.	Methyl group is mainly present in which photosynthetic pigment?(a) Chlorophyll b(b) Xanthophyll(c) Carotenoids(d) Chlorophyll aThis question was addressed to me in an interview.This is a very interesting question from Pigments Involved in Photosynthesis topic in section Photosynthesis in Higher Plants of Biology – Class 11
Answer» The correct answer is (d) Chlorophyll a Best explanation: Methyl group CH3 is MAINLY present in chlorophyll a. But in chlorophyll b, it has an aldehyde group in the C7 position. Chlorophyll a and b STRUCTURE mainly differs in the SUBSTITUENT of porphyrin.
