- Two
- Three
- Four
- Five
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Hemoglobin is a quaternary structure protein made of several polypeptide chains.
Step 2: Composition
It contains two identical \(\alpha\)-chains and two identical \(\beta\)-chains.
Step 3: Total
\(2+2=4\) subunits, option (C).
Final Answer:
Hemoglobin has four subunits. \[ \boxed{\text{(C) }\text{Four}} \]
