Opsonization.
Explanation:
- Complement proteins and antibodies coat a microorganism and provide binding sites, enabling macrophages and neutrophils to phagocytize the organism. This phenomenon is termed opsonization.
Opsonization occurs as a result of binding of a molecule called opsonin to the epitope of a pathogen.
Opsonization helps the immune system to select and kill the infected cells instead of targeting all the cells in general.
The major function of the immune system is to protect the host from environmental agents such as microbes or chemicals, thereby preserving the integrity of the body. This is done by the recognition of self and response to non-self.
