Easy question, timed assignment, please answer ASAP.
Thanks.
42. The phosphoglyceride depicted below is: H2C CH, a. phosphatidylcholine b. phosphatidylethanolamine d. phosphatidyIserine c. phosphatidylinositol none of the above e. 43. Cell membranes typically display asymmetry. What does this mean? two leaves of the bilayer contain different collections of lipids and proteins. atty acyl chain on C-1 of a membrane lipid is usually different from that on C-3. a. The ly one stereoisomer is ever seen at the chiral C-2 of the glycerol residue in a membrane lipid. Membrane lipids only have cis double bonds, never d. e. All of the above 44. Molecules that are components of functional proteins as well as complex lipid molecules include c. N-acetyl galactosamine eall of the above d. a&c a. serine b. sphingosine 45. Ouabain inhibits the action of the Nat/K primary transporter. Cells treated with Ouabain would also likely display decreased rates of diffusion abnormal function of voltage gated channels decreased rates of passive transport decreased rates of secondary active transport more than one of the above is possible a. b. c. d. e. Dehydrogenase enzymes facilitate the removal of hydrogens from their substrate. Which coenzyme may be required for this transfer? a. biotin b. FMNH2 46. c. FAD d. thiamine pyrophosphate e. NADH The carbohydrate component of glycoprotein may be attached to the polypeptide through an O- glycosidic bond. Which amino acid and sugar is likely to take part in this O-glycosidic bond? a. asparagine& N-acetylgalactosamine b. lysine& N-acetylglucosamine 7. threonine & N-acetylgalactosamine aspartate & N-acetylglucosamine d. e. c. serine & N-acetylglucosamine
