AP BIOLOGY

Detailed explanation-1: -In the AB blood group, both the antigens A and B are present on the red cells of the individual, and the serum contains neither anti-A nor anti-B antibodies.

Detailed explanation-2: -blood group AB – has both A and B antigens, but no antibodies.

Detailed explanation-3: -Your ABO blood type is based on the presence or absence of the A and B antigens on your red blood cells. The A blood type has only the A antigen and the B blood type has only the B antigen. The AB blood type has both A and B antigens, and the O blood type has neither A nor B antigen.

Detailed explanation-4: -It’s the universal donor. Group AB can donate to other AB’s but can receive from all others. Group B can donate red blood cells to B’s and AB’s.

Detailed explanation-5: -Blood group antigens are either sugars or proteins, and they are attached to various components in the red blood cell membrane. For example, the antigens of the ABO blood group are sugars. They are produced by a series of reactions in which enzymes catalyze the transfer of sugar units.
