Which of the following correctly describes the structure of the phospholipid bilayer in plasma
membranes?
The polar hydrophilic groups of each leaflet face outward, toward the aqueous
environment on either side of the membrane.
A
The non-polar hydrophobic groups of each leaflet face inward, toward each other.
The non-polar hydrophilic groups of each leaflet face outward, toward the aqueous
environment on either side of the membrane.
B
The polar hydrophobic groups of each leaflet face inward, toward each other.
The polar hydrophilic groups of each leaflet face inward, toward each each other.
The non-polar hydrophobic groups of each leaflet face outward, toward the aqueous
environment on either side of the membrane.
The non-polar hydrophilic groups of each leaflet face inward, toward each each other.
The polar hydrophobic groups of each leaflet face outward, toward the aqueous
environment on either side of the membrane.
Choose all that aplly that are TRUE for the lipid bilayer:Negative mark is given to incorrect answer(s).
a.
The polar head groups of the bilayer are positively charged.
b.
Individual lipid molecules in one face (monolayer) of the bilayer cannot diffuse (flip-flop) to the other monolayer and must be catalyzed by a lipid transporter called flippase.
c.
The bilayer is stabilized by covalent bonds between neighbouring phospholipid molecules.
d.
Polar, but uncharged, compounds readily diffuse across the bilayer.
e.
Individual lipid molecules are free to diffuse laterally on the surface of the bilayer.
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.
