b) If you soak an animal cell that is permeable to both water and glucose in either 5.5% glucose or 0.9% NaCl (both isosmotic solutions), the cell exposed to 5.5% glucose will gain water, while the cell exposed to 0.9% NaCl will not gain water. Predict why this is the case.
Choose which one Hypotonic, Hypertonic, Isotonic
1) Draw a model of the plasma membrane to form a cell. Include a tube embedded in the membrane. Show 2 water molecules inside the cell and 12 water molecules outside the cell. Indicate which way the water will move through the aquaporin with an arrow. a) Using your knowledge of membrane transport, which direction will the water molecules move through the aquaporin? Why? b) Why would water have a difficult time crossing the cell membrane? Keep in mind the structure of water in your answer. 2) Develop an explanation for the necessity of having kinks in the hydrophobic tail of the phospholipids that make up cell membranes. a) Develop an explanation for the necessity of having kinks in the hydrophobic tail of the phospholipids that make up cell membranes.
If two solutions separated by a semi-permeable membrane are isotonic, can you conclude that they are in chemical equilibrium?
In the experimental conditions described below, how many molecules of dextrose do you have to add to the extracellular fluid in order to make it iso-osmotic relative to the intracellular fluid? Intracellular fluid: • Number of water molecules = 60 • Number of Dextrose molecules = 8 • Number of Sucrose molecules = 4 Extracellular fluid: • Number of water molecules = 160 • Number of dextrose molecule = ???? • Number of Sucrose molecules = 0 Enter the number of molecules of dextrose in your answer (format: for 7 enter 7 or 7.00, for 7.5 enter 7.5 or 7.50, for 7.3333 enter 7.33 etc.). Your Answer:
A cell with a total of 0.2 osmol/L is placed into a solution with a total of 0.3 osmol/L (switched from the previous question). It is assumed that the osmotic particles cannot pass through the cell membrane. Answer the following true or false questions. 1. Solvent is more concentrated in the cell 2. Water will osmose out of the cell 3. The cell will shrink and may look crenated 4. Plant cells have a cell wall to protect them from dehydration caused by osmosis
The transport of a molecule is investigated using two chambers (left and right) separated by a synthetic membrane containing transport proteins. A solution containing varying concentrations of the molecule is added to the left side while pure water is added to the right. The transport rate of the molecule is determined by measuring the concentration of molecule that accumulates on the right side. The following table summarizes the transport rate of the molecule at various concentrations. Based on this you can conclude: a) the molecule is most likely transported by facilitated diffusion b) the molecule is moving across the membrane by passive transport c) the membrane is freely permeable to the molecule d) the molecule is most likely transported by active transport
The beaker is divided into two compartments (C and D) that has equal volumes of solution separated by an artificial membrane that has a pore size of 23 Å (Angstrom). Explain the movement of solute after eight hours if comparment C has 17 % sucrose while the compartment D has 2 % sucrose (diameter of sucrose molecule = 9 Å (Angstrom))
Can you predict water movement based on the relative osmolarities of two solutions? Why or why not?
Shown below are cells (colored) that were recently placed into a beaker containing a clear solution For each scenario, indicate whether movement of the molecule into the cell will occur using facilitated diffusion or active transport. А. B. 125mM 20mM fructose glucose 85MM 35mM fructose glucose OA= facilitated diffusion; B= facilitated diffusion OA= active transport; B= active transport O A= active transport; B= facilitated diffusion A= facilitated diffusion; B= active transport
Given the following cell type and solutions, draw the cell, showing the net direction of osmosis (water flow) and say what state the cell will be in. Choose from the following terms to describe the state of the cell: Turgid, flaccid, plasmolyzed, crenulated (shriveled), lysed (burst), normal. An animal cell with an internal osmolarity of 0.32 M (total concentration of all the solutes in solution) that is placed in a solution of 0.32 M NaCl.
