Antigens A and B are called: Bbl6epuTe oAMH OTBeT: a. Agglutinogens b. Agglutinins c. Fibrinolysins d. Enzymes

The correct answer is a. Agglutinogens.<br /><br />Antigens A and B are called agglutinogens. Agglutinogens are substances found on the surface of red blood cells that can cause the immune system to produce antibodies against them. These antibodies are called agglutinins. When the antibodies bind to the corresponding antigens on the surface of the red blood cells, they cause the cells to clump together, or agglutinate. This is the basis for blood typing and blood transfusion compatibility testing.
