Bacteria coated with complement and immunoglobulin; phagocytosis is enhanced by: AIIMS 11
|A||Receptor mediated endocytosis|
|C||Myeloperoxidase mediated destruction|
|D||C3b-Fc mediated destruction|
Complement, especially C3b and IgG, quoting the bacteria, act as opsonins and enhance phagocytosis because of the presence of receptors for C3b and Fc part of IgG on the surface of macrophages and neutrophils.
