Question:
Mg is an important component of which biomolecule occurring extensively in living world?
Mg is an important component of which biomolecule occurring extensively in living world?
Show Hint
Chlorophyll has Mg at its centre, while haemoglobin has Fe at its centre.
Updated On: Jan 5, 2026
- Haemoglobin
- Chlorophyll
- Florigen
- ATP
Show 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: \[ \boxed{\text{Chlorophyll}} \]
