Question 19
In adaptive immunity, which cells directly destroy virally infected cells? A. B cells B. plasma cells C. T helper cells D. T cytotoxic cells
Worked Solution & Example Answer:In adaptive immunity, which cells directly destroy virally infected cells? A - VCE - SSCE Biology - Question 19 - 2019 - Paper 1
Step 1
D. T cytotoxic cells
Answer
The cells that directly destroy virally infected cells are T cytotoxic cells. These cells recognize and kill infected cells by releasing cytotoxic substances. Unlike B cells, which produce antibodies, T cytotoxic cells play a crucial role in the cell-mediated immune response by targeting and eliminating cells displaying viral antigens.
