Part C Overview
The purpose of this portion of the lab was to observe how different temperatures affected the enzyme catalase. From the experiments with the boiling, warm, and ice water bath it proves that different types of temperatures have different sorts of effects on catalase. For instance, boiling water brings the reaction rate from a 5 to a 0, warm water brings the reaction rate from a 5 to a 4, and the ice water bath brings the reaction rate from a 5 to a 3, proving that different temperatures have different effects and reactions with the enzyme catalase.
Boiled Liver
This photo shows when we took liver and put it on the bottom of a clean test tube, put a small amount of water over it and boiled it for five minutes. The point of this part of the experiment was to see how temperature would effect the enzyme catalase. After we added 2ml of hydrogen peroxide, and the reaction rate was 0. Meaning that there was little to no reaction at all.
Ice water vs. warm water bath
In this picture the 2 test tubes to your left are filled 1 with beef liver and 1 with 2ml o hydrogen peroxide that has been put in a warm water bath (not boiling ) for 3 minutes. In the 2 test tubes to your right you have the same substances but have been put in an ice water bath for 3 minutes. Once the three minutes were up we added the cooresponding hydrogen peroxide with beef liver and the warm water produced a reaction rate of 4 and the ice bath a reaction rate of 3.
Conclusion
I think we can conclude that the more far away the temperature is from room temperature (or extreme temperatures such as boiling and freezing) creates the catalase to break down or denature and not work properly. But when they were in the water bath which was closer to room temperature it created a very similar reaction rate to the control in part A.
