Catalase Reaction Lab Report
Research Question: What is the activation energy (kJ mol-1) of the decomposition of hydrogen peroxide (H2O2) to oxygen (O2) and water (H2O) by catalyzed by catalase, by measuring the time taken for 10cm3 of oxygen gas to be evolved (s) at different temperatures (K) of 297.0K, 300.0K, 303.0K, 306.0K and 309.0K?
1: INTRODUCTION
When studying the function of catalysts in reactions during the kinetics unit, I was eager to know more about the position of enzymes, which function as biological catalysts in biological systems. After doing some further research, I found that catalase, an enzyme, which is found in nearly all living organisms such as animals, catalyses the decomposition of hydrogen peroxide (H2O2) in the blood. H2O2 is produced by reactions in the white blood cells in our body to fight against diseases. However, if H2O2 were to build up, it would potentially kill us. Fortunately, we have catalase, which decomposes H2O2 into water (H2O) and oxygen …show more content…
This oxygen is used by glucose oxidase in eggs to catalyse the oxidation of b-glucose to glucono-1,5-lactone, which spontaneously hydrolyses to gluconic acid, reducing the browning in egg products such as mayonnaise (Chaplin, 2014). Considering the importance of the decomposition of H2O2 with catalase, I questioned the worth of the activation energy of the catalyzed reaction (EA), which led me to my research question; What is the activation energy (kJ mol-1) of the decomposition of hydrogen peroxide (H2O2) to oxygen (O2) and water (H2O) when catalyzed by catalase, by measuring the time taken for 10cm3 of oxygen gas to be evolved (s) at different temperatures (K) of 297.0K, 300.0K, 303.0K, 306.0K and

    Background: The four different activities to the enzyme catalyst lab have similar but different backgrounds. Activity A’s background is to investigate the specific reaction of the decomposition of hydrogen peroxide by the enzyme, catalase. Hydrogen Peroxide decomposes slowly into water and oxygen, and the addition of catalase lowers the activation energy of the reaction until it proceeds to a room temperature. The catalase will is unchanged and is usable for to catalyze the reaction of more hydrogen peroxide. The background of activities A, B, and C is to determine the concentration of H2O2 in a solution. To do this, the concentration of an unknown will be used, such as a solution of 0.1 N, which is normal. When titration is done, 5 mL of acid will go in a beaker. When pH indicator paper is added, the paper will turn yellow if it is an acid and green if the solution is neutral. This is the endpoint of titration. In the activities, 2% potassium permanganate will be used to titrate H2O2. When the H2O2 reacts with the potassium…

    Effect Of Catalase Concentration Naomi Nikeeta Phagau

    3. Catalase is an antioxidant enzyme, which is naturally produced in most organisms, used to help break down hydrogen peroxide into oxygen and water. The break down of hydrogen peroxide helps prevent the accumulation of carbon dioxide bubbles in the blood. It is considered to have a great impact because it is capable of decomposing millions of hydrogen peroxide molecules. In addition, it uses the hydrogen peroxide to oxidize harmful toxins within organisms, such as formaldehyde, alcohol, and phenol.…

    Catalase Lab Report

    Enzymes are biological catalysts or assistants that consist of various types of proteins that work to drive the chemical reaction required for a specific action or nutrient. They can either launch a reaction or speed it up. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS). The catalase used in this experiment will come from five different sources: Spinacia oleracea (Spinach), Brassica oleracea (Broccoli), Solanum tuberosum (Russet Potato), Malus domestica (Apple), and Allium cepa (Onion). The five different catalases from the sources will all be used to catalyze Hydrogen peroxide (H2O2). When hydrogen…

    Have you ever wondered why the inside of your apple turns brown if you leave it on the counter after taking a bite? This is because there is a compound within the apple called catechol which, when exposed to the air, becomes oxidized by the oxygen in the air and produces benzoquinone, which makes the apple appear brown (Andrew Clapper’s Online Journal, 2007). This chemical reaction is catalyzed by the enzyme catechol oxidase (Figure A.1). Enzymes are proteins in cells that speed up chemical reactions (Enzyme Procedure Guide, 2013). The catechol oxidase lowers the amount of energy needed in order for the catechol to be oxidized, which speeds the process up.…

    The purpose of this lab was to test if ethanol affects the reaction involving hydrogen peroxide and catalase. Tests were performed by putting chicken liver, ethanol solution (diluted ethanol solution for other trials) and hydrogen peroxide in a test tube with a side arm, and having a rubber tube lead the oxygen gas into a gas collection tube. Results from the tests showed a negative correlation, this means that the more diluted the solution of 95% ethanol was, the less oxygen gas collected. Controlling a number of factors which include human error, temperature change, pH levels, substrate concentrations and ensuring a controlled experimental environment will work to increase the accuracy of the experiment.…

    In this experiment, my lab partners and I tested how time effects a catalase reaction. The amount of hydrogen peroxide was recorded after the reaction for the certain time given has taken place. We used sulfuric acid to stop the reaction with the catalase from occurring. This process is known as denaturing (Campbell 152). The potassium permanganate in this experiment was used as hydrogen peroxide indicator. It determined the amount of hydrogen peroxide remaining after the reaction occurred. Based on our experiment we observed that the time does play a crucial role on the catalase reaction because as we increased the time of the reaction, the amount of hydrogen peroxide decreased.…

    In this lab, we studied the activity of an enzyme that is found in fruits and vegetables called catecholase or catechol oxidase. An enzyme is a protein molecule that is a catalyst. Catechol oxidase is the enzyme in fruits and vegetables that turns them that undesirable brownish color; also commonly referred to as bruising or bruised. When walking through your regular grocery store and you find yourself in the produce section, what is it that you look for before putting that produce in the bag for weighing? The size, the smell, the color? Most of us would have to say that if they grabbed an apple that had a bruised body, they would return that apple to the pile in search for that perfect skinned apple. This is why studying catechol oxidase is so important!…

    An enzyme is something that helps to speed up a chemical reaction. The enzyme changes from reaction to reaction, but it always has the same impact. However, certain variables may cause the enzyme to have a more or less significant impact on the speed of each reaction. One of these variables that changes the effectiveness of an enzyme is temperature. There is an optimal functioning temperature for each enzyme in each reaction, depending on the desired change in speed. For some, this temperature is higher, and others lower. However, once this optimal temperature has been passed, the enzyme becomes less effective. A good comparison for the impact of temperature would be running. There is an optimal temperature at which every runner runs. If it is too hot or too cold, the runner may not run as fast as they could if it were, for example, 10 °C. However, the reason temperature impacts enzymes in that matter is due to kinetic energy. As the temperature increases, the kinetic energy also increases. At the optimal temperature, the molecules are moving as fast as they can without breaking bonds. If the speed is surpassed, bonds begin to break and the enzyme becomes less effective.…
