Question

What is the function of the lysozyme present in mucus?

• A. Degrade bacterial peptidoglycan
• B. Bind to iron
• C. To generate toxics
• D. Secretes an antibody

Hint:

Lysozyme is an important enzyme in the immune system that helps break down bacterial cell walls by targeting peptidoglycan, providing an essential defense against infections.

Answer 1

The Correct Option is A

Lysozyme is an enzyme found in various body fluids, including mucus. It plays an important role in immune defense by breaking down bacterial cell walls.
(1) Degrade bacterial peptidoglycan: This is the correct function of lysozyme. It cleaves the peptidoglycan layer of bacterial cell walls, leading to bacterial lysis. This is the correct answer.
(2) Bind to iron: This is not the primary function of lysozyme. Iron binding is typically associated with proteins like transferrin and ferritin, not lysozyme.
(3) To generate toxics: Lysozyme does not generate toxins. It is involved in breaking down bacterial cell walls, not in the production of toxins.
(4) Secretes an antibody: Lysozyme does not secrete antibodies. Antibodies are produced by B-cells, not by lysozyme.
Conclusion: The correct answer is Option 1: Degrade bacterial peptidoglycan as this is the function of lysozyme.
