Q. All enzymes are protein which are
✅ Correct Answer: (A)
globular
Explanation:
Enzymes are primarily globular proteins.
- Globular proteins are spherical or oval-shaped and are water-soluble, which makes them suitable for biochemical reactions.
- Enzymes function as biological catalysts, speeding up chemical reactions in living organisms.
- Their specific 3D structure allows them to bind with substrates efficiently.
Why not the other options?
- (B) Fibrous – Fibrous proteins (like collagen, keratin) provide structural support, but they are not enzymes.
- (C) Helical – Some enzymes may have helical structures (like alpha-helices in their secondary structure), but not all enzymes are helical.
- (D) All of these – Incorrect because enzymes are mainly globular, not fibrous.
Thus, the correct answer is (A) Globular.
