Essay On Catalase

973 Words2 Pages

Introduction
I am picking this topic because I have an interest in enzymes and how they work and how they help us in the world today. The different reactions that you can get from using enzymes and other substances intrigue me. The fact that it reduces prises levels in fruit Juice Company’s is amazing. It is also a great way to see food that have a high H2O2 level in them and find out what foods are bad for the body. I have found it interesting that from what I have been thought in class my come to help me do my ORT.

Topic
This experiment is to see the reactions of the catalyst from different substances or food groups when mixed with H2O2 and different acids. This will be done by using different substances that have high levels of catalyse enzymes. Substances with high levels of catalyst enzymes are Liver, yeast and Cabbage.

Sub Questions

1. What kind of liver will be used?
2. How long will the experiment take?
3. Why does hydrogen peroxide foam when you put it on a catalase?
4. What happens to H2O2 in the processing of the catalase?
5. What acids have the most effect on the Catalyse?

Hypothesis: liver will have the height’s amount of Catalase and the most amount of Foam for all 3 experiments, Catalase + H2O2
Aim: in this experiment is to use this reaction to see what substances have high levels of the Catalase enzymes and if different acids and basses are added would affect the reaction and the enzyme.
Apparatus:
Scale
Blender
Steering Rod
Ruler in cm
6 X 10 ml measuring cylinder

Conclusion
The Liver has the highest amount of Catalase and the most amount of Foam for all 3 test tubes and all 3 experiments. With all three of the Catalase the reaction made bubbles the bubbles you see in the foam are pure oxygen bubbles being created by the catalase. From the experiment you can see the Sodium Hydroxide had a big effect on the three different catalysts. It broke down the Yeast and Cabbage so much that hardly any reaction happened, the yeast was broken down so bad that no reaction happened so if you increased the amount or time with the Sodium Hydroxide with the liver it may do the same thing. But with the liver a slow but a big reaction happened. With the bubbles being water (H2O) and oxygen gas (O2). With all my findings it shows that the liver out of all the three catalyst holds the most catalyst and has the biggest reaction.
