Question

Which of the following is not true about the following?

• A. Chlorophyll ‘b’ contains aldehyde groups in their side chains
• B. Chlorophyll ‘a’ contains methyl groups in their side chains
• C. Chlorophyll ‘a’ contains aldehyde groups in their side chains
• D. Chlorophyll ‘a’ and chlorophyll ‘b’ contains the metal ion magnesium

Hint:

Chlorophyll is essential for photosynthesis, with chlorophyll ‘a’ directly involved in the light reactions and chlorophyll ‘b’ assisting in light absorption.

Answer 1

The Correct Option is C

Chlorophyll ‘a’ contains a methyl group, not an aldehyde group, in its side chains. Chlorophyll ‘b’ contains an aldehyde group. Both chlorophylls contain a magnesium ion at the center of their porphyrin ring structure.
