A)Memory T cells remember the specific foreign antigen.
B)Antibodies are produced by helper T cells.
C)Complement fixation is activated.
D)No T cells are involved.

Question

Quizplus · Accepted Answer

Complement fixation is part of the mechanism of antibody-mediated immunity, where complement proteins bind to the antibodies bound to the antigen, leading to the destruction of the antigen. Memory T cells (A) are involved in cell-mediated immunity, not antibody-mediated immunity. Antibodies are produced by B cells, not helper T cells (B). T cells are not directly involved in antibody-mediated immunity, but they may help activate B cells to produce antibodies. (D) is incorrect as T cells play a role in the activation of B cells and the subsequent production of antibodies.
