Question

Quizplus · Accepted Answer

Haptens are small molecules or incomplete antigens that can bind to larger molecules (such as proteins) in the body, causing an immune response that may be harmful rather than protective. Antibodies are proteins produced by the immune system in response to antigens, not harmful molecules. Pyrogens are substances that can cause fever. Interferons are proteins that can interfere with viral replication and activate immune responses, they are not harmful molecules that may mount an attack.
