    In this lab we attempted to find a relationship between pH and the productivity of the enzyme catalase. We used the method of testing called the ‘submarine’ method, and tested the velocity of the reaction in bubbles per 30 seconds. We measured this data by inserting 1 mL of H2O2, 1 mL of a vinegar and water solution that varies in pH, and 1 mL of H2O with 20 µL of liver puree into a narrow-mouthed piped base, dropped that into a flat bottomed test tube filled with 30 mL of distilled room temperature

    Jocelyn Yee Block 6 Enzyme Catalase Background Catalases are enzymes that stop cell oxidative damage. In some cases, they help by reducing hydrogen peroxide into water and oxygen gas. (Journal of the American Chemical Society, 2009). They are present in anything that is exposed to oxygen. Though oxygen is used to power cells, they become dangerous if not controlled. If electrons are transferred, they are easily converted into dangerous substances such as hydrogen peroxide which attack vital atoms

    As we study biomolecules, the subject of how do enzymes work comes up. The reasoning behind the catalase enzyme lab was to see how enzymes break down compounds. My objective being to see how the catalase enzyme will react to liver, potato and apple. We will also use a base or acid to see how these factors will affect the independent variable. My hypothesis is the liver and potato will react to the peroxide but the apple will not. In order to complete this lab, you will need the following materials;

    Introduction: Within a cell, enzymes are used as a catalyst to increase the rate of chemical reaction. They do not consume themselves, rather they help in increasing the rate of reaction. Within the body, enzymes vary depending on their specific functions. For instance, hydrogen peroxide is a toxic chemical, but it breaks down into harmless oxygen and water. This reaction can be sped up using the enzyme catalyst produced by yeast. Hydrogen peroxide is produced as a byproduct in cellular reaction

    Catalase Enzyme Activity

    As illustrated in Table 1, increase in temperature resulted in the increase of the rate of catalase activity to a certain range. After the range, the temperature would continue to increase, but the rate of catalase activity will decrease significantly. Rate of enzyme activity increased as temperature increased is supported by the Collision Theory. The collision theory states in order for a reaction to occur, reacting particles must collide with one another (McGraw-Hill Ryerson Chemistry 12). Particles

    Enzymes are a type of protein that assist in chemical reactions and speed them up. Catalase is an enzyme that breaks down hydrogen peroxide (H2O2) in water and oxygen. Enzymes can denature if their pH or temperature change to an intolerable level. This is when the enzyme’s shape changes so the subtrate can not fit into it. Subtrates need to fit into the enzyme for the enzymes to be useful in reactions, or else they are useless. The goal of this study was to observe how the enzyme activity would be

    Practical Investigation Enzyme Catalase Activity Brontë Smith C13 06|05|2015     Abstract Five different temperatures of enzyme (spinach extract) (5°C, 20°C, 35°C, 45°C and 65°C) were added to individual measuring cylinders -each filled with 7ml of Hydrogen Peroxide (H202). The height of foam (oxygen + water) produced by the reaction was recorded for each temperature of the catalase after 30 seconds, to find at which degrees the enzyme activity had the fastest reaction rate. The data

    The catalase enzyme is so critical to our health that it is found in nearly every living organism on the planet that is exposed to oxygen. This antioxidant enzyme can catalyze the conversion of hydrogen peroxide into water and oxygen. Hydrogen peroxide is a by-product of cell metabolism, which serves some useful functions including healthy immune response. (Group, 2013) Catalase has one of the highest rates of turnover when compared to all other enzymes. In other words, one catalase enzyme can change

    Organisms use enzymes in order to break down potentially harmful materials in the body and to carry out chemical reactions. One such process that involves substances and enzymes in the body is processing H2O2 by the liver and other body systems into water and oxygen. In an enzyme catalysis lab, the goal was to find out how, as time passes, how much H2O2 will be left over after reacting with the enzyme catalase. Samples from various times were used in order to stop the catalysis sulfuric acid (H2SO4)

    Catalase Enzyme Lab Introduction The human body is an incredible system that is capable of working a multitude of diverse functions. Without the help of the many different protein molecules, the human body would not be able to function properly. One major group of proteins called enzymes are mandatory for essential life. These proteins are constantly at work assembling molecules, metabolizing energy, and fighting off infections. An enzyme is a macromolecule that acts as a catalyst that
