Membrane attack complexes (MAC) form holes in attacked cells causing them to burst; this is a result of ________.
A) interferon
B) complement fixation
C) natural killer cells
D) keratin
E) phagocytes

Question

Quizplus · Accepted Answer

Membrane attack complexes (MAC) are formed through the process of complement fixation, which involves a cascade of proteins that ultimately lead to the formation of the MAC. The MAC creates holes in the attacked cells' membranes, causing them to burst. Interferons help to protect uninfected cells from viral infections, natural killer cells are involved in the destruction of infected or abnormal cells, keratin is a structural protein found in skin, hair, and nails, and phagocytes are cells that engulf and destroy foreign particles. None of these are directly involved in the formation of MACs.
