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.

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.
Acting as the controlled group to lessen the effects of all variables except the independent variable, at 0% concentration, the height of foam produced is 0 mm. Attributions to these results is because at 0% substrate concentration, no molecules were present to occupy all the available active sites. As an outcome, the final volume of oxygen is none since there were no collisions taken place between the enzymes and substrate. Therefore, prevented the number of collisions to reach the activation energy.
The purpose of this study is to analyze the activity of the enzyme, catalase, through our understanding
Catalase is a common enzyme that is produced in all living organisms. All living organisms are made up of cells and within the cells, enzymes function to increase the rate of chemical reactions. Enzymes function to create the same reactions using a lower amount of energy. The reactions of catalase play an important role to life, for example, it breaks down hydrogen peroxide into oxygen and water. Our group developed an experiment to test the rate of reaction of catalase in whole carrots and pinto beans with various concentrations of hydrogen peroxide. Almost all enzymes are proteins and proteins are made up of amino acids. The areas within an enzyme speed up the chemical reactions which are known as the active sites, and are also where the
With this information we were able to identify any patterns and similarities. Hypothesis: The higher the temperature of water, potato and H²O², the rate at which the Enzyme will work will be faster therefore producing more oxygen. The reaction will be the same without the catalase (potato). Therefore in both experiments the Enzyme will work more rapidly and produce more oxygen. Aim: To test the hypothesis.
In this experiment as a whole, there were three individual experiments conducted, each with an individualized hypothesis. For the effect of temperature on enzyme activity, catalase activity will be decreased when catalase is exposed to temperatures greater than or less approximately 23 degrees Celsius. For the effect of enzyme concentration on enzyme activity, a concentration of greater or less than approximately 50% enzymes, the less active catalase will be. Lastly, the more the pH buffer deviates from a basic pH of 7, the less active catalase will be.

Investigating Factors that Affect the Rate of Catalase Action Investigation into the factors which affect the rate of catalase action. Planning Aim: To investigate the affect of concentration of the enzyme catalase on the decomposition reaction of hydrogen peroxide. The enzyme: Catalase is an enzyme found within the cells of many different plants and animals. In this case, it is found in celery.
In this lab, it was determined how the rate of an enzyme-catalyzed reaction is affected by physical factors such as enzyme concentration, temperature, and substrate concentration affect. The question of what factors influence enzyme activity can be answered by the results of peroxidase activity and its relation to temperature and whether or not hydroxylamine causes a reaction change with enzyme activity. An enzyme is a protein produced by a living organism that serves as a biological catalyst. A catalyst is a substance that speeds up the rate of a chemical reaction and does so by lowering the activation energy of a reaction. With that energy reactants are brought together so that products can be formed.
Abstract: Enzymes are catalysts therefore we can state that they work to start a reaction or speed it up. The chemical transformed due to the enzyme (catalase) is known as the substrate. In this lab the chemical used was hydrogen peroxide because it can be broken down by catalase. The substrate in this lab would be hydrogen peroxide and the enzymes used will be catalase which is found in both potatoes and liver. This substrate will fill the active sites on the enzyme and the reaction will vary based on the concentration of both and the different factors in the experiment. Students placed either liver or potatoes in test tubes with the substrate and observed them at different temperatures as well as with different concentrations of the substrate. Upon reviewing observations, it can be concluded that liver contains the greater amount of catalase as its rates of reaction were greater than that of the potato.
The Effect of pH on the Activity of Catalase Planning Experimental Work Secondary Resources Catalase is a type of enzyme found in different types of foods such as potatoes, apples and livers. It speeds up the disintegration of hydrogen peroxide into water because of the molecule of hydrogen peroxide (H2O2) but it remains unchanged at the end of the reaction.
How the Concentration of the Substrate Affects the Reaction in the Catalase Inside Potato Cells
The purpose of this experiment was to study the reactions of amino acids and aspartame. Several solutions were prepared and used in TLC analysis. A permanganate test and a ceric nitrate test were also performed. The summary of the results is shown below.
We left these cups sit for twenty- four hours and then we observed them. The second experiment we set up involved dialysis tubing which was acting like a membrane. In the dialysis tubing we put a liquid that was made of starches and sugars. We then put the dialysis tubing into a beaker of water wh... ... middle of paper ... ...
Without enzymes, reactions wouldn’t occur and living organisms would die. For instance, the enzyme in the stomach breaks down large molecules to smaller molecules to absorb nutrition faster. Researchers experimented with enzyme activity with a potato extract. Researchers will test enzyme activity by increasing and decreasing pH levels, lowering and increasing temperature, and substrate concentration effects. In the first experiment, researchers hypothesized whether different pH levels would change how much Benzoquinone are created and how will the enzymes function in neutral pH levels than higher and lower levels. Researchers used potato extract and different levels of pH to test their hypothesis. In addition, researchers questioned at what temperature does the greatest amount of potato extract enzyme activity take place in. Researchers then hypothesized that the results would indicate the greatest amount of potato enzyme activity level will take place in room temperature. In this experiment, researchers used potato extract and different temperature levels to test the hypothesis. Moreover, researchers wanted to test the color intensity scale and how specific catechol oxidase is for catechol. In this experiment, researchers used dH2O, catechol solution, hydroquinone, and potato extract. Lastly, researchers tested the substrate concentration and how it has an effect on enzyme activity. In this experiment researchers used different measurements of catechol and 1cm of potato extract. Researchers hypothesized that the increase o substrate would level out the enzyme activity
