Easy question, timed assignment, please answer ASAP.
Thanks.
4. The type(s) of lipid(s) attached to lipid linked proteins include a. fatty acids attached via cys residues. b. fatty acids attached to the N-terminal gly residue c isoprene d. b& e. all of the above. groups attached via a C-terminal cys residues 49. Which of the molecules given below is the fiber of the human diet? a. amino acids b. triacylglycerols e. waxes c. amylopectin d. cellulose 50. Aspirin produces most of its analgesic effects by b. inhibiting the synthesis of arachidonate. c. inhibiting the synthesis of phospholipids. d. inhibiting the synthesis of eicosanoids e. inhibiting transmission of pain signals to the brain. 51. W hich glycosaminoglycan is found in the synovial fluid surrounding joints where it acts as a lubricant? a. Chondroitin Sulfate b. Dermatan Sulfate c. Heparin d. Hyaluronic Acid e. Keratan Sulfate 52. Which vitamin is a required coenzyme for the hydroxylation of proline and lysine amino acids in collagen? a. niacin b. vitamin C c. vitamin K d. riboflavin e. vitamin E 53. Which statement regarding membrane structure and function is correct? a. Proteins can be anchored to the membrane by a polysaccharide bridge between a phosphatidylinositol molecule and the protein. The glycocalyx of the membrane is associated with the inner leaflet of the membrane. Phosphatidylcholine and the sphingomyelins are especially rich in the inner leaflet of the membrane. Cholesterol decreases the fluidity of the membrane. The cytoskeleton is a complex dynamic arrangement of protein fibers associated with the outer leaflet of the membrane. b. c. d. e. Which of these statements about primary active transport across a membrane is true? a. b. 54. It can increase the size of a transmembrane concentration gradient. The rate of transport always increases as the concentration of molecule to be transported increases. c. A specific membrane protein mediates the movement of the molecule through the membrane d. a &c e. All of the above
