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.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
