Question

The process of coating pathogens to mark them for phagocytosis by macrophages is termed:

Options

• Precipitation

• Opsonisation

• Hypersensitivity

• Agglutination

Answer 1

Opsonisation is the antibody function that coats the surface of pathogens, effectively marking them for destruction. This coating enhances recognition and phagocytosis by macrophages and other phagocytic cells, making it easier for immune cells to engulf and eliminate the pathogen.
