Question

Proteins that help in the destruction of the infected cells are

• A. Caspases
• B. Lysozymes
• C. Colostrum
• D. Interferons

Hint:

Caspases are crucial in the immune system's response to infections by initiating apoptosis to remove infected or damaged cells. They are a vital part of the body's defense mechanism.

Answer 1

The Correct Option is A

Caspases are a family of enzymes that play an essential role in programmed cell death (apoptosis). They help in the breakdown of infected or damaged cells. Caspases activate the process of apoptosis, ensuring the elimination of infected or abnormal cells, making them key in immune responses.

Lysozymes are enzymes that break down the cell walls of bacteria, but they do not directly contribute to the destruction of infected cells. They play an important role in the immune system but act more as an antimicrobial agent.

Colostrum is the first milk produced by mammals after giving birth, rich in antibodies, but it does not directly help in the destruction of infected cells.

Interferons are proteins produced by cells in response to viral infections, and while they help modulate the immune response and inhibit virus replication, they do not directly destroy infected cells.

Conclusion: The correct answer is Option A: Caspases.
