1. An artificial "cell" consisting of an aqueous solution enclosed in a selectively permeable membrane is immersed in a beaker containing a different solution, the "environment," as shown below.. The membrane is permeable to water and to the simple sugars glucose and fructose but impermeable to the disaccharide sucrose. a. Draw the solid arrows to indicate the net movement of the solutes into and/or out of the cell. b. Is the solution outside the cel!l isotonic, hypotonic, "Cell" "Environment" 0.01 M sucrose 0.03 M sucrose or hypertonic? 0 02 M glucose 001 Mglucose 0.01 Mfructose c. Draw a dashed arrow to show the net osmosis, if any.

Match the following statement related to membrane transport processes to the appropriate term or terms: passive transport, facilitated transport, active transport. A transporter (or carrier) protein is necessary. (Select all that apply.) passive transport facilitated transport active transport O O

Describe the similarities and differences between the dialysis bag and a cell membrane. Be specific. If you want water to flow out of a dialysis bag filled with a 50 percent sucrose solution what would be the minimum concentration of the beaker solution need to be?

6. As a demonstration, an artificial cell consisting of an aqueous solution enclosed in a semi permeable membrane is placed into a beaker containing a different solution. The membrane is permeable to water and to monosaccharide's glucose and fructose but completely impermeable to the disaccharide sucrose. The concentration of each cell is described in the diagram below. 0.03M Sucrose 0.02M Glucose 0.01M Sucrose 0.01M Glucose 0.01M Fructose a. Which solute(s) will exhibit a net diffusion into the cell? Explain. b. Which solute(s) will exhibit a net diffusion out of the cell? Explain. C. Which solution is hypertonic, the cell or the solution? Explain.
