Question

Which enzymes play a key role in target cell destruction during cell mediated immunity?

• A. Perforin and catalase
• B. Lysozyme and catalase
• C. Granzyme and helicase
• D. Perforin and granzyme

Hint:

Remember: Perforin forms pores, and granzyme triggers apoptosis during cell-mediated immune responses.

Answer 1

The Correct Option is D

During cell-mediated immunity, cytotoxic T lymphocytes and natural killer cells destroy infected or cancerous cells using enzymes.
Perforin forms pores in the target cell membrane allowing granzyme to enter.
Granzyme induces apoptosis (programmed cell death) within the target cell.
