Updated On: Jan 5, 2026
- Haemoglobin
- Chlorophyll
- Florigen
- ATP
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Role of magnesium in biology.
Magnesium is the central metal ion in the porphyrin-like ring structure of chlorophyll.
Step 2: Compare with haemoglobin.
Haemoglobin contains iron (Fe) as central metal, not Mg.
Step 3: Therefore correct biomolecule.
Chlorophyll is present in plants and is essential for photosynthesis.
Final Answer: \[ \boxed{\text{Chlorophyll}} \]
