Question:
Myosin(s) is/are
Myosin(s) is/are
Show Hint
Contractile proteins like myosin and actin are examples of fibrous proteins.
Updated On: Apr 16, 2026
- fibrous proteins
- globular proteins
- enzyme
- Both (a) and (b)
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Myosin is a major component of muscle fibers and is a motor protein. Proteins are classified into fibrous and globular based on structure.
Step 2: Detailed Explanation:
Myosin is a fibrous protein. It has a long, rod-like tail (fibrous domain) and a globular head domain that binds to actin and hydrolyzes ATP. While it has a globular region, the overall protein is classified as fibrous due to its elongated shape and structural role in muscle contraction. It is not an enzyme in the typical sense, though the head domain has ATPase activity.
Step 3: Final Answer:
Myosin is a fibrous protein, which corresponds to option (A).
