    Essay On Catalase

    • 1288 Words
    • 3 Pages

    communicate with each other by keeping the life and death of the cell under control. What is the substrate of catalase? A substrate is a substance in which an enzyme reacts. A catalase is an enzyme that destroys harmful substances inside your body. Hydrogen peroxide (H_2 O_2) is produced in the body because of the reactive nature of oxygen. Oxygen atoms that are lost can be used to produce this. Catalase converts H_2 O_2 into the water and oxygen gas, thus, protects the DNA. Describe three safety factors

    The Effects of pH on Catalase Activity Problem and introduction: Catalase is an enzyme in living plants and animals that speeds up the breakdown of hydrogen peroxide (H2O2). The breakdown of hydrogen peroxide is essential to living organisms because hydrogen peroxide is toxic to cells. The chemical reaction for the decomposition of hydrogen peroxide is having the substrate hydrogen peroxide catalyzed by the enzyme catalase to produce the products, water and oxygen. What effect does pH have on the

    attempted to extract and purify the protein catalase from a bovine liver by following a procedure involving homogenization, ammonium sulfate fractionation, dialysis, a UNO Q-12 FPLC anion exchange column, and a Superdex G75 2.6 X 60 gel filtration column. In total, 45 mL or 895 mg of catalase was obtained over the course of the experiment. The specific activity of the purified catalase was 0.260 units/mg (Table 1). The final pooled fraction of catalase obtained was 45 mL, a highly significant yield

    Aim: To study the effect of substrate concentration on the activity of the enzyme catalase, which is found in living tissues and cells. In this experiment we will obtain catalase from yeast cells. The substrate will be hydrogen peroxide (H202), which vary concentrations from 1-10%. We will measure the rate of reaction by the volume of oxygen (02) released into the water. Catalase will do this reaction: 2H2O2 2 H2O2 + O2

    enzymes, also known as protein molecules, is to aid in the conversion of reactants to products by catalyzing the chemical reaction. In the experiment conducted in the BZ 310-L06 laboratory the enzyme catalase, which converted hydrogen peroxide into the products water and oxygen, was analyzed. The catalase enzyme was subjected to varied substrate concentration, inhibitors, and varied temperatures to determine the effects of the environment on the enzyme’s ability to function. The enzyme was first observed

    toxic to cells in high levels due to how readily it transforms to a hydroxyl radical, OH- (5). Catalase is an enzyme whose job is to break down hydrogen peroxide, so it does not convert to the hydroxyl radical. When hydrogen peroxide is present in the cell, catalase catalyzes a reaction that transforms hydrogen peroxide into water and oxygen gas. This reaction causes bubbles to form (4). Without catalase, hydrogen peroxide can kill the

    The Catalase Experiment Aim: The aim of this experiment is to find out what affect the temperature has upon the speed of the decomposition of hydrogen peroxide when a biological catalyst is used; the enzyme catalase. Back ground: ============ Hydrogen peroxide is a decomposition reaction. This means that the hydrogen peroxide, if left for long enough, will eventually decompose. Hydrogen peroxide → Hydrogen + Oxygen 2H2O2→2H2O + O2 (Aq) (L) (G) Using a catalyst

    Enzyme Catalase Background information: An enzyme is a large protein that acts as a biological catalyst and which changes the rate of a reaction. It provides an active site which is an environment where a reaction can take place this is made up of amino acids. The structure and shape of the substrate, the structure and shape of an enzyme and the substance upon which the enzyme works all have to match exactly. This enables the substrate to bind, but it can't do this if the shapes of the two
