• A. bacteria
• B. fungi
• C. protists
• D. viruses

Hint:

Lysozyme is an enzyme found in tears and other bodily fluids that breaks down bacterial cell walls, aiding in immune defense.

Answer 1

The Correct Option is A

Step 1: Understanding the function of lysozyme.
Lysozyme is an enzyme found in bodily fluids such as tears, saliva, and mucus. It breaks down the cell walls of bacteria, causing them to lyse (burst).
Step 2: Analyzing the options.
(A) bacteria: Correct. Lysozyme is primarily responsible for breaking down bacterial cell walls.
(B) fungi: Incorrect. Lysozyme is not effective against fungi.
(C) protists: Incorrect. Lysozyme does not target protists.
(D) viruses: Incorrect. Lysozyme does not act on viruses.
Step 3: Conclusion.
The correct answer is (A) bacteria, as lysozyme is effective in lysing bacterial cells.
