Interpretation Introduction
Interpretation: The correct polarity-based description for the interior of a lipid bilayer has to be stated.
Concept introduction: A lipid bilayer involves polar heads of the lipid components and non-polar tails of the lipid components. The surface position is occupied by the “heads” and the internal positions are occupied by the “tails”.

- Ms. Sassa, a biology professor, wanted to demonstrate to her students the applicability of a dialyzing membrane (DM) as a model for the cell membrane by enclosing an aqueous solution in a DM bag and immersing in a beaker containing a different solution. Substances available which are permeable to the DM include 0.02 M NaCl, 0.03 M glucose, and 0.01 M glucose. The only substance available which is completely impermeable to the DM is the 0.01 M lactose. Using the substances given and materials such as a beaker, stirring rod, and string, draw ONLY ONE set-up that can be demonstrated by Ms. Sassa that will satisfy ALL of the following conditions: a. No solute will exhibit a net diffusion out of the cell. b. Glucose will exhibit a net diffusion into the cell. c. NaCl will exhibit a zero net movement. d. No net movement of lactose from the inside to outside of the cell. Make sure to label properly the substance inside the beaker and inside the DM bag.arrow_forwardWhich 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. Transbilayer diffusion involves the transfer of lipids from one face of the bilayer to another.arrow_forwardYou make a phospholipid bilayer with short, unsaturated hydrocarbon tails. You measure the permeability of this membrane to oxygen and water, which are normally somewhat able to cross the membrane. You then saturate the hydrocarbon tails, and re-measure membrane permeability. You then double the length of the saturated hydrocarbon tails again, and make a third measurement of membrane permeability. You graph membrane permeability (Y) as a function of hydrocarbon tail length (X). Which of the graphs below best represents the data you expect?
