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 coordinating the immune response. Upon encountering a pathogen, these cells become activated and can stimulate both B lymphocytes to produce antibodies and activate cytotoxic T lymphocytes. This process is essential for an effective immune response, making option (B) the correct choice.
