Which of the following molecules released by T cytotoxic cells will enter a virus-infected cell through pores and break down proteins?ANSWERGranzymesCytokinesInterferonsPerforins

The molecule that is released by T cytotoxic cells and will enter a virus-infected cell through pores to break down proteins is Granzymes.

Here's a step-by-step explanation:

1. T cytotoxic cells are a type of white blood cell that play a key role in the immune system's response to infected or cancerous cells.

2. When a T cytotoxic cell identifies a virus-infected cell, it releases certain molecules to destroy the infected cell.

3. One of these molecules is Granzymes.

4. Granzymes are serine proteases, a type of enzyme that breaks down proteins.

5. These Granzymes can enter the virus-infected cell through pores created by another molecule released by T cytotoxic cells, called Perforin.

6. Once inside, the Granzymes will break down proteins to induce apoptosis, or programmed cell death, effectively killing the virus-infected cell.

So, the answer to your question is Granzymes.
