binding
site
V C
Heavy chain
V
Light chain
S.S.
Fc (stem) region c C Hinge region
None of the other four answers (All are
true statements)
Antibodies (Immunoglobulins) are composed
of four protein molecules, two identical "light"
chains and two identical "heavy" chains
Antigens bind to the "stem", composed of
the constant regions of the two "heavy"
chains
The variable (V) regions form the antigen
binding sites
The constant (C) regions determine class of
antibody
