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

- 21-85 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_forward21-100 What are the functions of a cell membrane? To what extent is a bilayer that consists entirely of lipids able to carry out these functions?arrow_forward21-87 Which statements are consistent with the fluid mosaic model of membranes? (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_forward
