    The purpose of this experiment was to see if there would be enzyme activity that is in catalase, which is found in potatoes. How my partner and me did the experiment was very simple, we put the filter paper filled with catalase concentration in to five sets of hydrogen peroxide. We found that the more concentration of hydrogen peroxide there was the faster it would take for the filter paper to reach the top, and the lower to no concentration level of hydrogen peroxide was the slower it would go to

    Environmental Effects on Enzyme Activity Introduction Enzymes are substances (most often proteins) that act as biological catalyst. A catalyst speeds up the rate of chemical reaction. This process promotes the conversion of reaction into products. Most of us know that hydrogen peroxide is a toxic chemical but catalase speeds up the breakdown of hydrogen peroxide into non-toxic substance such as water and oxygen. In this catalase enzyme vs. hydrogen peroxide experiment we ask, what environmental

  • The Effect of Temperature on the Activity of the Enzyme Catalase

    1594 Words  | 4 Pages

    Temperature on the Activity of the Enzyme Catalase Introduction: The catalase is added to hydrogen peroxide (H²0²), a vigorous reaction occurs and oxygen gas is evolved. This experiment investigates the effect of temperature on the rate at which the enzyme works by measuring the amount of oxygen evolved over a period of time. The experiment was carried out varying the temperature and recording the results. It was then repeated but we removed the catalase (potato) and added Lead Nitrate

  • Effect Of Enzyme Concentration On Catalase

    933 Words  | 2 Pages

    Background Information Enzymes are proteins that serve as biological catalysts in a wide variety of life sustaining chemical reactions that take place in cells. As catalysts, enzymes lower the activation energy it takes a chemical reaction to occur. Because of this enzymes serve to speed up the rate at which the chemical reactions can occur. However, enzymes are substrate specific. This means only one kind of enzyme will bond with one kind of substrate on the active site, the place where the chemical

  • The Effect Of Enzyme Experiment On Catalase Concentration

    1613 Words  | 4 Pages

    At the time of conducting the experiment, the intention was to analyse the effect that an increase in catalase concentration had on the amount of oxygen (O2) produced if the hydrogen peroxide (H2O2) concentration was constant. It was proposed that when the catalase increases in concentration at the increments of 0.5%, 1%, 2%, and 4% and the hydrogen peroxide remained at a fixed concentration, the oxygen production would rise gradually. It was suggested that this would occur due to the collision theory

  • The Effect of the Enzyme Catalase on Hydrogen Peroxide When the Temperature is Changed

    893 Words  | 2 Pages

    The Effect of the Enzyme Catalase on Hydrogen Peroxide When the Temperature is Changed Plan: Chemical reactions take place in all living cells. All of these reactions are enzyme-driven. Some of these reactions produce by-products. One by-product is Hydrogen Peroxide (H2O2). It is a poison and must be removed from the cells. The cell produces an enzyme called Catalase to break down the Hydrogen Peroxide into water and oxygen. This experiment will investigate the effect of temperature on

  • What Factors Affect the Decomposition of Hydrogen Peroxide by The Enzyme Catalase Which is Found in the Liver

    Factors Affect The Decomposition Of Hydrogen Peroxide By The Enzyme Catalase Which Is Found In The Liver" Introduction: Enzymes are biological catalysts. They speed up the chemical reactions which go on inside living things. Without them the reactions would be so slow that life would grind to a halt. Enzymes work by when a substrate molecule bumps into a molecule of the right enzyme, it fits into a depression on the surface of the enzyme molecule. This depression is called the active site. The reaction

  • Analysis of the Decomposition Rate of Hydrogen Peroxide With Catalase As a Catalyst

    654 Words  | 2 Pages

    Rate of Hydrogen Peroxide With Catalase As a Catalyst Aim: To measure the rate of decomposition of Hydrogen Peroxide with Catalase from a Yeast solution using PH as a variable. Hypothesis: The enzyme Catalase speeds up the Hydrogen Peroxide decomposition as its active sites match the shape of the Hydrogen Peroxide molecule. This process will only work at certain PH levels as the Enzyme sites may become disfigured at extremes. Logic suggests that Catalase will work well at PH7 Neutral,

    produced when hydrogen peroxide is broken down by the enzyme catalase. A large piece of potato will contain a higher amount of catalase than a smaller piece and therefore produces a greater volume of oxygen. The Task Design an experiment to show that an increase in the concentration of catalase affects the volume of oxygen released from hydrogen peroxide. Hypothesis I predict that as you add more potato , the concentration of the catalase increases resulting in an increase of the volume

    oxygen from hydrogen peroxide using the enzyme catalase Introduction Hydrogen peroxide is poisonous to all living things if it builds up in the cells but when it is introduced to the enzyme catalase the react between the two makes water and oxygen as byproducts. There are many factors witch affect the production of oxygen these are listed below. For this experiment the enzyme will be held in potato. Prediction I predict that the enzyme catalase will have a temperature at which it will

    Aim and Hypothesis The investigation that we have chosen to do is how the effect of temperature affects the rate of reaction of hydrogen peroxide to water and oxygen using the enzyme catalase. I predict that the higher the temperature the faster the rate of reaction will be and the more oxygen there will be given off. I've based this prediction on kinetic theory (every 10 degree rise in temperature the rate of reaction doubles

    Purpose: This lab gives the idea about the enzyme. We will do two different experiments. Enzyme is a protein that made of strings of amino acids and it is helping to produce chemical reactions in the quickest way. In the first experiment, we are testing water, sucrose solution, salt solution, and hydrogen peroxide to see which can increase the bubbles. So we can understand that enzyme producing chemical reactions in the speed. In the second experiment, we are using temperature of room, boiling water

  • Biological Effects on Potato

    2775 Words  | 6 Pages

    Biological Effects on Potato Potatoes, like all other vegetables contain the enzyme catalase, which breaks down the toxic waste product of hydrogen peroxide. Potatoes have an unusual response to long exposures of light, where the chemical properties are altered within the cells. This can be seen as the surface changes green in colour. Storage conditions of potatoes are therefore important, to ensure potatoes remain in the original state after cultivation. Within this assessment, the effects

  • Methods Of Enzyme Activity Of Sweet Potato And Carrot

    Enzyme activity rates differ depending upon the type and concentration of extracts and distilled water. Previous experiments have shown that starches in greater concentrations have high enzyme activity. With that, it can be hypothesized that sweet potatoes have a higher enzyme activity level than that of carrots. Materials and Methods Three different sweet potato and carrot samples were finely diced up separately, using a scalpel. Upon cutting them into smaller pieces, they were measured into 50
