Worked Solution & Example Answer:What is a possible immune response to a pathogen? (A) T lymphocytes produce antibodies - HSC - SSCE Biology - Question 13 - 2001 - Paper 1
Step 1
B) T helper lymphocytes are activated.
Answer
T helper lymphocytes play a crucial role in the immune response. When a pathogen invades the body, these cells are activated by recognizing antigens presented by antigen-presenting cells. This activation leads to the proliferation of T helper cells, which subsequently stimulate B cells to produce antibodies and activate cytotoxic T cells, facilitating efficient immune defense. Thus, option (B) correctly describes a possible immune response.
