All of the following correctly describe the structure of an antibody molecule except:
A)two identical light chains
B)heavy and light chains held together by disulfide bonds
C)binds 2 antigens per molecule
D)two Fc fragments and one Fab fragment

Question

Quizplus · Accepted Answer

Antibody molecules have two identical heavy chains and two identical light chains that are held together by disulfide bonds. Each heavy and light chain has variable and constant regions. The variable regions of the heavy and light chains together form the antigen-binding site or Fab fragment, which is where the antibody binds to its target. The Fc fragment is the constant region of the antibody that is responsible for activating immune cells and other effector mechanisms. Antibody molecules have two Fab fragments and one Fc fragment, not two Fc fragments and one Fab fragment.
