When antibodies bind antigens, the clumping of antigens results from
A)the multivalence of the antibody having at least two binding regions.
B)disulphide bridges between the antigens.
C)complement that makes the affected cells sticky.
D)bonds between class I and class II MHC molecules.
E)denaturation of the antibodies.

Question

Quizplus · Accepted Answer

The multivalence of the antibody, having at least two binding regions, allows for cross-linking of antigens and the formation of clumps or aggregates. This is known as agglutination. Disulphide bridges, complement, bonds between MHC molecules, and denaturation of antibodies do not play a role in clumping of antigens.
