66. The extracellular matrix, the surfaces of animal/human cells, and the associated polysaccharides have several properties. Which of the following is NOT applicable? a. Molecules on one cell recognize and respond to molecules on another adjacent cell. b. Molecules on a cell recognize and respond to molecules in the extracellular matrix. c. The extracellular matrix is not the simple outer layer of the cell membrane. d. Many of the interactions of the cell surface and extracellular matrix proteins involve sugar-attached glycoproteins on the cell surface and proteoglycans in the extracellular matrix. e. In some glycoproteins, the carbohydrates attached are "prosthetic".

Which of the following does not apply for the carbohydrate-containing cell-surface and extracellular matrix proteoglycans? a. The "information" held in the sugar moieties is encoded directly in the genes, just like it is encoded in the proteins. b. The specific function and information of the carbohydrate moieties are determined by the expression of the appropriate enzymes that assemble carbohydrate units in characteristic ways. c. The glycoproteins may contain covalently linked oligo and polysaccharide groups. d. Not all glycoproteins have O-linked saccharides. e. Both a and d do not apply.
