Question

Blood group agglutinogens A and B are found

• A. In plasma
• B. On WBC's
• C. On RBC's
• D. On blood platelets

Answer 1

The correct option is C On RBC's

Agglutinogens A and B are the glycoproteins found on the surface of red blood cells. These are also known as A and B antigens and on the basis of these antigens, four blood groups are classified as A, B, AB and O. Antigens A and B bind to specific antibodies called agglutinins and this process is called agglutination. In blood type A, antigen A is present on RBCs while in blood type, antigen B is present on RBCs. In blood type AB, both antigens A and B are present on RBCs and no antigen is present on RBCs in O blood type.

So, the correct answer is 'On RBCs'.
