Question

In an antigen-antibody interaction, when a univalent (monovalent) antigen interacts with a multivalent antigen, what is the typical outcome?

A. Stronger binding and more effective immune response
B. Weaker binding and reduced immune response
C. No interaction occurs
D. The antigen becomes inactive
E. The antibody is destroyed

Answer 1

When a univalent antigen interacts with a multivalent antigen in an antigen-antibody interaction, the typical outcome is weaker binding and reduced immune response.

Step-by-step explanation:

In an antigen-antibody interaction, when a univalent (monovalent) antigen interacts with a multivalent antigen, the typical outcome is weaker binding and reduced immune response. This is because multivalent antigens have multiple binding sites, allowing them to bind with multiple antibodies simultaneously. As a result, the binding between a univalent antigen and a multivalent antigen is weaker compared to the binding between two multivalent antigens, leading to a reduced immune response.
