antibodies binding to their antigen can activate complement. this, in turn, leads to opsonization of the antigen-antibody complexes. what is meant by opsonization? multiple choice clumping together of the antibody-antigen complexes. lysis of the cells bearing the antibody-antigen complexes. clumping of antibody-antigen complexes into insoluble substances. coating antibody-antigen complexes, making them more easily phagocytized by macrophages and neutrophils.

a specific kind of immune cell that can encircle and eliminate bacteria, consume foreign objects, and eliminate dead cells. It may also strengthen immunological responses. Phagocytes include monocytes, macrophages, and neutrophils. One kind of white blood cell is the phagocyte.

Opsonization is an immunological procedure in which opsonins are used to mark foreign pathogens for phagocyte eradication. The negatively charged cell walls of the pathogen and phagocyte reject one another in the absence of an opsonin, such as an antibody. Complement is a system of plasma proteins that can be activated by pathogens directly or indirectly through an antibody that is bound to the pathogen. This activation of complement causes a series of reactions to take place on the surface of pathogens, which produces active components with various effector functions. Inflammation is caused by the recruitment of immune cells, opsonization and phagocytosis by C3b deposition, bacterial lysis by C5b-9 complex formation, activation of endothelial and epithelial cells, and activation of platelets as a result of complement activation.
