When antibodies bind antigens, the clumping of antigens results from ________.
A) the antibody having at least two binding regions
B) disulphide bridges between the antigens
C) bonds between class I and class II MHC molecules
D) denaturation of the antibodies

Question

Quizplus · Accepted Answer

The clumping of antigens, also known as agglutination, occurs when antibodies bind to multiple antigens, causing them to aggregate. This happens because most antibodies have at least two binding regions, allowing them to bind to multiple antigens simultaneously. Disulphide bridges between antigens and bonding between class I and class II MHC molecules are not involved in agglutination, and denaturation of antibodies would prevent them from binding to antigens altogether.
