9. Water moves across a cell membrane through a channel protein, whereas glucose moves across a cell membrane via a carrier protein. Which statement provides a valid comparison of these two membrane transport systems? 田 Glucose moves in a direction from high to low concentration, while water moves in a direction that is not governed by differing solute concentrations. Water transport OCcurs without the cell using energy, whereas glucose transport requires energy input by the cell. A cell can add more sites for water transport to increase water movement across the membrane but cannot achieve the same result for glucose using a similar strategy. Several water molecules move one after the other through the opening provided by a channel protein, while glucose is transported across the membrane via a carrier protein one molecule at a time. Genetic mutations can alter glucose transport into a cell but cannot alter water transport.

DO NOT COPY THE ANSWER FROM THE SAME QUESTION. 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 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.
