People who have the AB blood type possess _____________. (Select all correct choices)
A)an enzyme that adds an N-acetylgalactosamine to the end of the oligosaccharide chain on RBC membrane glycolipids
B)an enzyme that adds a galactose to the end of the oligosaccharide chain on RBC membrane glycolipids
C)an enzyme that adds phospholipids to the end of the oligosaccharide chain on RBC membrane glycolipids
D)no enzymes capable of attaching galactose or N-acetylgalactosamine to the end of the oligosaccharide chain on RBC membrane glycolipids

Question

Quizplus · Accepted Answer

People with the AB blood type have both the A and B antigens on their red blood cells, which are determined by the presence of different sugars (specifically N-acetylgalactosamine and galactose) on the end of the oligosaccharide chain on RBC membrane glycolipids. Therefore, individuals with the AB blood type possess the enzymes that add both sugars to the end of the oligosaccharide chain. They do not have an enzyme that adds phospholipids to the end of the oligosaccharide chain on RBC membrane glycolipids.
