Highlight the structural importance of an antibody molecule with a diagram. Name the four types of antibodies found to give a humoral immune response, mentioning the functions of two of them you have studied.

Question : Highlight the structural importance of an antibody molecule with a diagram. Name
the four types of antibodies found to give a humoral immune response, mentioning the functions of two of them you have studied.

The correct answer is – An antibody molecule consists of four polypeptide chains, two are long
called heavy (H) chains while other two are short called light (L) chains.
Both are arranged in the shape of Y. Hence, the antibody is represented
as H2 L2.
