Antibodies play an important role in fighting microorganisms and other pathogens. To which type of protein do they belong?
Correct answer: A. Globular
- A. Globular
- B. Functional
- C. Fibrous
- D. Both Options A and B are correct
Explanation
Antibodies belong to a group of globular proteins in serum or plasma; they are therefore also known as immunoglobulins. Antibodies react specifically with antigens, which are responsible for the production or induction of those specific antibodies.

About Proteins
Proteins are polymers of amino acids joined by peptide bonds, and their function depends on primary, secondary, tertiary and quaternary structure. The topic covers fibrous and globular proteins, enzymes, antibodies, hormones and transport proteins, as well as denaturation by heat or extreme pH.
