Which Statement Best Describes What Causes the Clumping of Antigens

Question

Which statement best describes what causes the clumping of antigens when antibodies bind antigens?
A) the antibody has two identical binding sites
B) disulfide bridges form between the antigens
C) bonds form between class I and class II MHC molecules
D) the antibodies denature

Accepted Answer

Antibodies have two identical binding sites that allow them to bind to two antigens simultaneously, leading to the clumping or agglutination of antigens. This is a fundamental aspect of the immune response, facilitating the identification and removal of pathogens.
