Question

In the process of agglutination, IgD antibodies ________.

A) remove the antigen from the pathogen
B) block access to the antigenic site
C) bind to antigens on two different cells
D) stimulate the release of histamine from mast cells
E) activate the complement system

Answer 1

In the process of agglutination, IgD antibodies bind to antigens on two different cells, clumping them together and preventing their proper functioning. This helps fight infection by marking the pathogens for destruction by phagocytes before they can infect cells.

Step-by-step explanation:

In the process of agglutination, IgD antibodies bind to antigens on two different cells. When IgD antibodies encounter antigens, they can create bridges between different particles containing antigenic sites, clumping them together and preventing their proper functioning. This process can fight infection by marking the pathogens for destruction by phagocytes before they can infect cells.
