Which Part of the Innate Response Cuts Holes in the Cell

Question

Which part of the innate response cuts holes in the cell membranes of pathogens?
A) complement proteins
B) histamines
C) antibodies
D) cytokines
E) fibrin

Accepted Answer

Complement proteins, a group of plasma proteins, are responsible for cutting holes in the cell membranes of pathogens, resulting in their lysis or destruction. This is part of the innate immune response. Histamines, antibodies, cytokines, and fibrin all play important roles in the immune response, but none of them are responsible for cutting holes in cell membranes.
