35 Group questions Your group used dialysis tubing to create a model "cell".  How does this model differ from a real cell.  Why does it differ? A. no cell wall dead, so no active transport From Osmobeaker simulation run on a lab computer, answer the following questions as a group. Part VIII: Doctor’s report. Let's say you wanted to save the next doctor who comes along some time figuring all this out. In the space below, write a short set of instructions on how to compose IV fluids based on your work in this lab. Part IX: Mystery Cell If you click on the Mystery RBC button on the left, you will be presented with a cell that contains water, hemoglobin, salt, and sugar. For a study you are doing, you want to know the concentration of solutes inside this cell, and in addition, you want to know how much of that solute is hemoglobin vs. simpler molecules like sugars and salts. This cell is somewhat more realistic than the previous ones, because you can’t see the molecules inside of it. However, using some of the techniques you have applied in this lab, you can put your knowledge of osmosis to work to answer the following 2 bonus questions: What is the solute concentration of the mystery RBC?  Show or describe how you figured this out in the space below. You have a drug that pokes very small holes into the membrane of the cell. These holes let salt and sugar molecules pass across the membrane along with water. To use your drug, click on the membrane as before. You will see 3 sliders for controlling the permeability of water, salt, and sugar, respectively. Drag all of these to the 50% position to make the membrane permeable to all 3. In this study, you can also add sugar and hemoglobin to your IV fluid. Given all of these new tools, can you figure out the concentration of hemoglobin inside the cell? Show or describe how you figured this out in the space below, attaching additional sheets if necessary.
