Quizplus · Accepted Answer

MAC (membrane attack complex) and killer T cells both puncture the membranes of foreign bacteria. Macrophages and helper T cells do not puncture membranes but rather engulf and destroy foreign invaders. Antibodies and plasma cells do not puncture membranes but rather tag foreign invaders for destruction by other immune cells. Antibodies and killer T cells do not both puncture membranes; antibodies bind to and neutralize foreign invaders while killer T cells directly attack and kill infected cells.
