Verified step by step guidance1
Understand the role of each term in the context of the immune system: Antibody, Antigen, Interferon, and Complement.
Recall that an antibody is a protein produced by B cells in response to a specific antigen, which helps neutralize or eliminate pathogens.
Recognize that an antigen is a molecule or molecular structure, often on the surface of pathogens, that triggers an immune response but is not produced by the body to protect against infection.
Know that interferons are proteins produced by host cells in response to viral infections to interfere with viral replication, but they are not the primary proteins that specifically target pathogens.
Understand that complement refers to a group of proteins in the blood that assist antibodies and phagocytic cells in clearing pathogens, but these proteins are not antibodies themselves.
