Question

What is the primary action of the complement-mediated lysis mechanism?

Options

• Neutralization of viral particles

• Marking pathogen for phagocytosis

• Pore formation in pathogen membrane

• Clumping of antigens

Answer 1

The primary action of complement-mediated lysis is pore formation in the pathogen membrane. When IgM or IgG activates the complement cascade, the resulting membrane attack complex creates pores that compromise the integrity of the pathogen's membrane.
