Summary Introduction
To analyze:
The movement of water from solution A to B or B to A.
Introduction:
Aquaporins or water channels are the proteins that help in the movement of water across the membrane. They are integral membrane proteins that form pores in the membrane to allow the transfer of water and sometimes small solutes.

- 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.

- Soft contact lenses are made from hydrogels, which make them soft and flexible. It is important to clean them daily using a sterile, isotonic cleaning solution. The concentration of solutes in the cleaning solution is the same as the concentration of the hydrogel in the contact lens. What would happen if instead of an isotonic cleaning solution, soft contact lenses are cleaned with water? (A) The soft contact lenses will shrink because it will remove too much water by osmosis. B The soft contact lenses will shrink because too much water is absorbed by osmosis. The soft contact lenses will swell and change shape because too much water is absorbed by osmosis. The soft contact lenses will swell and change shape because too much water is removed by osmosis.arrow_forwardIn the experiment showing osmosis through a semipermeable membrane, 3 corn syrup mixtures are used.
