On the red blood cell surface, ABO blood group antigens are carried on which type of molecule?
Show answer and explanation
Correct answer: Glycoproteins and glycolipids
ABO blood group antigens are oligosaccharide chains attached to both glycoproteins and glycolipids on the red cell membrane; the immunodominant terminal sugars (for example N-acetylgalactosamine for the A antigen) determine specificity.
