Question

What is the primary action of opsonization?

Options

• Activation of the complement cascade directly

• Pore formation in the pathogen membrane

• Clumping of antigens together

• Marking the pathogen for phagocytosis

Answer 1

The primary action of opsonization is to mark the pathogen for phagocytosis. When antibodies coat the surface of an antigen, they serve as signals that enhance recognition and uptake by phagocytic cells.
