Vedclass · Answer

(B) An antibody molecule has a $Y$-shaped structure consisting of four polypeptide chains: two heavy chains and two light chains.Each antibody molecule contains two antigen-binding sites located at the tips of the $Y$-shaped structure,known as the variable regions.Because there are two specific binding sites,each antibody molecule can bind to a maximum of two antigen molecules simultaneously.Therefore,the correct answer is $2$.

How many antigens can each antibody molecule bind to at most?
