Which of the following is true about motion of membrane lipids? A. They can move most rapidly when in the gel phase. B. Lateral diffusion is catalyzed by flippase proteins. C. To increase the fluidity of membranes at low temperatures, cells synthesize more saturated fatty acids and fewer unsaturated fatty acids. D.

How does the phospholipid bilayer of a liposome differ from the phospholipid bilayer of the plasma membrane of a cell? (a) The phospholipid bilayer of a liposome contains only phospholipids, without the proteins that are embedded in the plasma membrane of a cell. (b) The phospholipid bilayer of a liposome contains two bilayers of phospholipid molecules, whereas the plasma membrane of a cell contains only one. (c) The phospholipid bilayer of a liposome completely envelops the liposome, whereas the plasma membrane of a cell does not completely envelop the cell. (d) The phospholipid molecules in the phospholipid bilayer of a liposome are oriented with the lipid ends on the outside of the bilayer and the phosphate groups on the inside.
Steroids such as Estrogen or Testosterone are lipids which are found in the cytoplasm of living cells. They can pass across (dissolve in) the proto cell and prokaryote phospholipid bilayer because they: a) perform dehydration synthesis, b) dissolve in water, c) are ionic, d) they a soluble in the Fatty Acids of the bilayer, e) none are true.
Which of the following does not apply to lipid asymmetry? a.It arises in the endoplasmic reticulum. b.It arises due to the flip-flop movement of specific phospholipids to the cytosolic monolayer. c.It is preserved throughout vesicular transport. d.It depends on the activity of flippase.
Which of the following best describes the lipid aggregates known as liposomes? A. They contain a hollow non-aqueous interior cavity. B. They are spherical structures with their hydrophobic regions aggregated in the interior cavity. C.
