Discussion and Conclusion Introduction: Background Information In the permeability lab, I gained an understanding of the principles of diffusion and osmosis.. Osmosis is the diffusion of water through a selectively permeable membrane from a region in which it is highly concentrated to an area that has a lower concentration.. Osmosis is important because it helps distribute nutrients and.
In conclusion to our data, you can see that the Dark Yellow solution is almost exactly the same as our mystery solution and that the molarity of the Light Yellow solution and the Blue Solution are both different compared to the mystery solution. There were no errors in our data this lab, but potential problems could be accidentally mixing solutions or the Dialysis tubing breaking while in the.
Conclusion For this experiment data was collected and analyzed using charts and graphs. According to the data and observations, the sugar diffused across the dialysis tubing but not the plastic bag, whereas the starch did not diffuse at all. In addition, the artificial cell gained weight over the course of an hour. This last outcome is a result of osmosis.
Lab 4: Enzyme Experiment Effect of enzyme concentration Data Table Effect of enzyme concentration on the production of gas Response to Question 1 Enzyme-Catalase produced by the yeast Substrate-Hydrogen peroxide Response to Question 2 The rate of reaction in tube 1 was rapid followed by tube 2 and in tube 3 it was the slowest. This difference was because of the differences in the concentration.
