Specific Antibodies are Highly Protective Molecules Because

Question

Specific antibodies are highly protective molecules because
A)of their ability to bind to specific antigens.
B)of their ability to enter all cells in the body.
C)one antibody molecule has more than 20 binding sites.
D)one antibody molecule can bind to many different antigens.
E)one antibody molecule is able to kill many bacterial cells.

Accepted Answer

Specific antibodies are highly protective molecules because they are able to bind specifically to a particular antigen, such as a virus, bacterium or toxin, and target it for destruction or removal by the immune system. This specificity ensures that the antibody only targets harmful pathogens or foreign substances, while leaving healthy cells alone. A single antibody molecule typically has two binding sites that recognize a particular antigen.
