Antibodies play important role against microorganisms and other pathogens to which type of proteins do they belong________?

Explanation

Antibodies are immunoglobulins that recognize antigens and help neutralize or remove pathogens. Their polypeptide chains fold into compact, soluble three-dimensional shapes, so they are classified as globular proteins rather than fibrous structural proteins. Students may choose b because antibodies contain disulphide bonds and have an elongated Y shape, but shape alone does not make them fibrous proteins.
