Vedclass · Answer

(A) The provided image represents the structure of an antibody molecule (immunoglobulin).An antibody molecule consists of four polypeptide chains: two small 'light chains' and two larger 'heavy chains', represented as $H_2L_2$.The variable region at the tips of the $Y$-shaped structure forms the 'antigen binding site' (labeled as $X$ in the diagram).The longer polypeptide chains forming the stem and part of the arms are the 'heavy chains'.Therefore, $X$ represents the antigen binding site and the longer chains represent the heavy chain.
