iii. These data suggest which of the following? a. The cells used in the study do not have membrane microdomains. b. Fillipin induces the formation of membrane microdomains. c. X-CFP and Y-YFP are near neighbors only when membrane microdomains are present. d. Cholesterol is required for X-CFP and Y-YFP to fluoresce. e. Cholesterol allows membrane proteins to diffuse away from membrane microdomains. State rational for your answer: The lateral structures of the plasma membrane component are membrane microdomains that are enriched with glycosphingolipids and cholesterol, containing glycosylphosphatidylinositol (GPI) - anchored proteins (Harder, 1998).

Which the following conditions would likely make a membrane least permeable? Low cholesterol content in membrane The presence of phospholipids containing long fatty acid tails in membrane None of these conditions influence membrane permeability The presence of phospholipids containing highly unsaturated tails in membrane
Adi S.
Which of the following is TRUE regarding how cholesterol affects the fluidity and permeability of biological membranes? a. At low temperatures, cholesterol causes phospholipids to pack more tightly together, and therefore, decreases membrane fluidity and permeability. b. At high temperatures, cholesterol increases the spacing between phospholipids and therefore, increases membrane fluidity and permeability. c. At low temperatures, cholesterol increases membrane fluidity and permeability by reducing the extent to which phospholipids pack tightly together. d. At high temperatures, cholesterol decreases membrane fluidity by reducing the extent to which phospholipids pack tightly together.
