1.	Observe the given diagram and answer the following questions:(1) What is I and II in the above diagram?(2) What structures are responsible for antigen and antibody complex? Identify them in the above diagram.(3) What is the study of antigen-antibody interactions called?
Answer» (1) I is a virus which is trying to cause infection, II are two antigen molecules which are trying to attack the virus. (2) (a) is epitope which is antigen determinant and (b) is a paratope which is part of the antibody. Epitope and paratope are specific to each other and hence they form a complex. (3) The study of antigen-antibody interactions is called serology.
