Chlorophyll a can be converted into chlorophyll b by replacing:
Correct answer: C. Methyl group with carbonyl group
- A. Carbonyl group with methyl group
- B. Magnesium with ferrous
- C. Methyl group with carbonyl group
- D. Ferrous with magnesium
Explanation
The primary structural difference between chlorophyll a and chlorophyll b is the presence of a methyl group (-CH3) in chlorophyll a, which is replaced by a carbonyl group (-CHO) in chlorophyll b. This change affects their light absorption properties, optimizing their roles in photosynthesis. The other options involve changes that do not occur in this conversion process.
