A)Complement fixation is activated.

C)Memory B cells remember the specific foreign antigen.
D)Cytotoxic T cells destroy a specific foreign antigen.

Question

Quizplus · Accepted Answer

Cell-mediated immunity involves the activation of cytotoxic T cells, which recognize and destroy cells that have been infected with a specific foreign antigen. This is in contrast to humoral immunity, which involves the production of antibodies by B cells. Complement fixation and opsonization are mechanisms involved in complement-mediated immunity, which is a separate aspect of the immune system. Memory B cells are also involved in humoral immunity, as they remember specific foreign antigens and can rapidly produce antibodies upon re-exposure.
