The characteristic function and properties of each class of antibody is determined by the
A)variable region on the light chain.

E)variable region on the heavy chain.

Question

The constant region on the heavy chain determines the class of antibody, such as IgG or IgE. The variable region on the heavy and light chains determine the antigen specificity and binding affinity. The epitope is the specific part of the antigen that the antibody binds to. The constant region on the light chain also plays a role in antibody function, but does not determine the class.
