Piper Gunderson 6-3-11 Biology Mr. Becker Yeast and Peroxide Catalase Lab Write-Up In yesterday’s experiment, we were given the opportunity to look at a catalase reaction. Catalase is an enzyme that is found in nearly every living thing that is near oxygen. During this experiment we took hydrogen peroxide and activated yeast and combined them in a beaker. When the peroxide was added, a tremendous amount of bubbling took place. This is because of the reaction between the enzymes and the peroxide that turns the peroxide into water and oxygen as shown below: 2 H 2 O 2 → 2 H 2 O + O 2 After it finished bubbling, you could add more peroxide and it would continue to bubble. This is because of a property of enzymes that states that they keep functioning and do not

Unformatted text preview: stop working unless they are denatured. They don’t run out of their power to achieve a certain function or goal. However if we were to boil the yeast solution, the bubbling response would not take place because the increased temperature would have denatured the yeast enzymes. In the final part of the experiment, we took the peroxide and yeast mixture and put it in a flask. We then added a stick that was just recently set on fire so it still was burning but not flaming. The stick caught back on fire for a brief period of time because of the oxygen that was given off by the reaction. This helped prove to us the development of oxygen gas when you add the hydrogen peroxide and yeast solution together....
