Concept explainers
Interpretation:
The reason due to which a person with type B blood can receive blood only from types B and O, but can donate to either type B or AB blood needs to be explained.
Concept Introduction:
Human blood is classified into 4 types A, B, AB and O. These blood types are determined by specific polysaccharides that are covalently bonded to a membrane protein in red blood cells. These polysaccharides contain the monosaccharide, D-galactose, L-fucose, N-acetyl-D-glucosamine and N-acetyl-D-galactosamine. Type A blood contains all four monosaccharide. Type B blood contains N-acetyl-D-glucosamine, two D-galactose units and L-fucose. Type AB blood has both type A and B carbohydrates. Type O blood contains N-acetyl-D-glucosamine, D-galactose and L-fucose.

(a) All membrane proteins are bound to the interior of the membrane. (b) Both proteins and lipids undergo transverse (flip-flop) diffusion from the inside to the outside of the membrane. (c) Some proteins and lipids undergo lateral diffusion along the inner or outer surface of the membrane.arrow_forward21-85 Which of the following statements is (are) consistent with what is known about membranes? (a) A membrane consists of a layer of proteins sandwiched between two layers of lipids. (b) The compositions of the inner and outer lipid layers are the same in any individual membrane. (c) Membranes contain glycolipids and glycoproteins. (d) Lipid bilayers are an important component of membranes. (e) Covalent bonding takes place between lipids and proteins in most membranes.arrow_forward
