cell. The organelle contain variety of enzymes which involved in different metabolic reaction. Peroximoses were named because of its enzyme contains that usually remove hydrogen atoms from particular organic substrates with molecular oxygen. This oxidative reaction will produce hydrogen peroxide. [pic] However, during “peroxidative” reaction (H2O2 + R′ H2 → R′ + 2H2O), catalase (an enzyme in peroxisomes) will capitalize on the H2O2 produced by other enzymes in the organelle, in order to oxidize

Title: Enzyme Introduction The main reason for conducting this experiment is to establish the various factors that affect enzymes and reaction rates. Various experiments have been conducted to help gain a wide range of the factors that affect enzyme controlled reactions. Enzymes are affected by very many factors. It was the main aim of this experiment to establish these factors and the manner in which they affect them. This experiment also seeks to establish the manner in which some enzymes

Enzyme Lab INTRODUCTION: What would happen to your cells if they made a poisonous chemical? You might think that they would die. In fact, your cells are always making poisonous chemicals. They do not die because your cells use enzymes to break down these poisonous chemicals into harmless substances. Enzymes are proteins that speed up the rate of reactions that would otherwise happen more slowly. The enzyme is not altered by the reaction. You have hundreds of different enzymes in each of your cells

Outline * Name of the enzyme: Catalase found in chicken liver. * The name of the organism is chicken (liver). * The substrate is hydrogen peroxide (H2O2)|. * Hypothesis: If the catalase in the chicken liver is exposed to hydrogen peroxide, it will cause a chemical reaction. This reaction will result in the destruction of hydrogen peroxide in the chicken liver, which is harmful to the cells; the enzyme catalase works best in acidic solutions and enzymes are denatured in very high

Effect of Temperature on Rate of Reaction of Catalase Abstract Properties of Enzymes focused on the variations of reaction rates amongst enzymes subjected to various circumstances such as temperature, pH levels, different concentrations of substrate, salt concentrations, Metal Copper Sulfate and lastly, the presence of an Enzyme Inhibitor. The assigned section of this laboratory for our efforts was the effect of temperature variations on enzyme reactions. To perform the experiment, we used a

LAB #3: An Enzyme in Plant and Animal Tissues BACKGROUND INFORMATION Liver and other living tissues contain the enzyme catalase. This enzyme breaks down hydrogen peroxide (H2O2), which is a harmful by-product of cellular respiration if it builds up in cells. In this lab, you will perform reactions with the enzyme catalase. OBJECTIVES: 1. Investigate the enzyme catalase in various tissues. 2. Measure the effect of changes in temperature on reaction rates of an enzyme-catalyzed reaction

This is because the hydrogen peroxide is substrate specific to catalase which is found in the liver solution tab. The two products react to create an active site which produces water and oxygen. Therefore, as the amount of hydrogen peroxide increased then the displaced oxygen will increase but eventually it should level out due to the effect of substrate concentration on enzyme activity (Allot, 99-100, 2014). Catalase is an enzyme that is found in the liver of animals and it aids to catalyze the

Catalase, a heme containing enzyme, is found in tiny organs inside of cells called peroxisomes. Catalase is found all over the human body. When catalase turns alcohol into acetaldehyde the hydrogen which is released is bound to hydrogen peroxide molecules which then become water. Although catalase is active everywhere in the body, catalase is of particular interest to researchers because it metabolizes alcohol in the brain. The acetaldehyde released into the brain by the metabolism of alcohol by

Introduction: This report will talk about the experiment that was conducted to see what percent of hydrogen peroxide had the greatest reaction with the potato cube. The enzyme in this experiment was catalase, which could be found inside of the potato cube. The substrate was the hydrogen peroxide. The role of the potato cube was to react with the hydrogen peroxide causing it to break down at a quicker rate which released oxygen (O₂). Three factors that could influence the enzyme’s activity is the

HOW ENZYMES FUNCTION SHANITA HAMLIN BIOL1402L-165 DR. MERCEDES MONDECAR 09/27/2012 INTRODUCTION: Enzymes are proteins produced by living cells, which regulate chemical reactions in the body. Enzyme activity can be affected by The experiments conducted were done to show that under optimum conditions; such as the ideal temperature, the right pH, and a higher enzyme or substrate concentration, the activity of the catalase enzyme would increase.
