Question

after a t cell has been activated for a specific antigen it __________. a produces cytokines b undergoes clonal expansion c produces antibodies d produces cytokines and undergoes clonal expansion

Explanation:

• Option A: Activated T cells do produce cytokines, but this is not the only thing they do.
• Option B: Activated T cells do undergo clonal expansion, but this is not the only thing they do.
• Option C: Antibody production is done by B cells, not T cells.
• Option D: After activation by a specific antigen, T cells produce cytokines (to help regulate the immune response) and undergo clonal expansion (to increase the number of T cells specific to that antigen). This option includes both key processes of activated T cells.

Answer:

D. produces cytokines and undergoes clonal expansion
