The process by which antibodies bind to specific sites on bacterial exotoxins to block their harmful effects is called:
|
|
Agglutination
|
|
|
Neutralization
|
|
|
Opsonization
|
|
|
None of These
|
Explanation:
Detailed explanation-1: -1: Neutralization of Exotoxins. The Fab portion of the antibodies made against epitopes of the binding site of an exotoxin blocks the exotoxin from binding to the exotoxin receptor on the host cell membrane. As a result, the toxin can not enter the cell and cause harm.
Detailed explanation-2: -Neutralization is defined as the loss of infectivity that takes place when an antibody molecule binds to a virion and usually does not require the involvement of any other antibody activity.
Detailed explanation-3: -1) Antibodies are secreted into the blood and mucosa, where they bind to and inactivate foreign substances such as pathogens and toxins (neutralization).
