Question

Quizplus · Accepted Answer

Opsonization is the process by which a pathogen is marked for phagocytosis by the immune system. It involves the coating of the pathogen with complement proteins, which act as opsonins and bind to specific receptors on the surface of phagocytes, facilitating their recognition and ingestion of the pathogen.
