Question

Quizplus · Accepted Answer

Opsonization refers to the process of marking antigens for phagocytosis by immune cells, but it is not the antibodies themselves that do the phagocytosis. Instead, opsonins such as complement proteins or antibodies enhance phagocytosis by binding to the antigen and making it more recognizable to immune cells.
