Q589
The chemical structure of chlorophyll a varies from chlorophyll b due to difference between
A.
CH3 and C2H5
B.
CH3 and CHO
AnswerC.
CHO and CH = CH2
D.
CH3 and HCH = CH2
Answer: Option B
Solution
Answer: Option B
Solution:
The chemical structure of chlorophyll a varies from chlorophyll b due to difference between CH3 and CHO.Chlorophyll a is a specific form of chlorophyll used in oxygenic photosynthesis. Chlorophyll b helps in photosynthesis by absorbing light energy.
In chlorophyll a, third carbon of the side group is -CH3. In chlorophyll b, side group at the third carbon is -CHO. It is more soluble than chlorophyll a in polar solvents because of its carbonyl group.
