Detailed explanation-1: -ABO blood grouping is based on differences in the type of glycoprotein (protein with carbohydrates attached) present on the surface of red blood cells. Type A individuals have type A glycoproteins; Type B individuals have type B glycoproteins; Type AB individuals have both; and Type O individuals have neither.
Detailed explanation-2: -Blood type is determined primarily by the presence of antigens A and B on the membranes of the blood cells. Blood type A has A antigen, blood type B has B antigen, blood type AB has both A and B antigen and blood type O lacks A and B antigen.
Detailed explanation-3: -Kidd antigen (known as Jk antigen) is a glycoprotein, present on the membrane of RBCs and acts as a urea transporter in RBCs and renal endothelial cells. Kidd antibodies are rare but can cause severe transfusion reactions.
Detailed explanation-4: -Red blood cell antigens determine your blood group The antigens expressed on the red blood cell determine an individual’s blood group. The main two blood groups are called ABO (with blood types A, B, AB, and O) and Rh (with Rh D-positive or Rh D-negative blood types).
Detailed explanation-5: -The correct answer is FALSE. Glycoproteins (antigens) on the surface of the red blood cells determine the type of blood of an individual. For instance, a person whole blood type is A has A antigen on the surface of his red blood cells.
