One molecule of haemoglobin can transport how many molecules of oxygen?
Show Hint
Haemoglobin: 4 subunits.
Each subunit binds 1 O\(_2\).
Total = 4 O\(_2\) per haemoglobin.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Haemoglobin is an oxygen-carrying protein.
Each molecule has a specific oxygen-binding capacity.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the structure of haemoglobin.
Step 3: Detailed Explanation:
One molecule of haemoglobin has four subunits.
Each subunit has one heme group.
Each heme group can bind one oxygen molecule.
Thus, one haemoglobin molecule can transport four oxygen molecules.
Step 4: Final Answer:
One molecule of haemoglobin transports four molecules of oxygen.
Hence, the correct option is (D).
