A 19-year-old man comes to the physician with a bacterial infection. Without treatment, the patient’s immune system will most likely be able to fight off the infection within a few days. One of the tools the patient’s body uses against the organism is the membrane attack complex. The membrane attack complex functions as which of the following?
(A) A chemoattractant for neutrophils
(B) An anaphylactic signal causing degranulation of mast cells
(C) An opsonization molecule, facilitating phagocytosis
(D) A proteinaceous pore in the plasma membrane
(E) A scaffold on cell membranes to which antibodies can bind
