  • Enzyme Catalysis And Its Effect On The Reaction Rate Of An Enzyme

    1178 Words  | 5 Pages

    TITLE: ENZYME CATALYSIS PURPOSE: Measure the effects of changes in catalase concentration, substrate concentration, and salinity on the reaction rates of an enzyme. RESEARCH COMPONENTS: What is being tested-what do you know about enzymes? PRELAB QUESTIONS: Explain how the structure of an enzyme is related to its function/activity. All enzymes are structured to react with unique substrates. and each enzyme has an active site where the substrate bonds to the enzyme. The active site of an enzyme

  • Lab Report on Measuring the Rate of Conversion of Hydrogen Peroxide using Enzyme Catalysis

    664 Words  | 3 Pages

    Lab Report on Measuring the Rate of Conversion of Hydrogen Peroxide using Enzyme Catalysis In essence, the main objective was to use chemical titration to measure and then calculate the rate of conversion of hydrogen peroxide (H2O2) to water and oxygen by using the enzyme catalase. Other purposes of the lab were; to measure the effects of changes of temperature, pH, enzymes concentration, and substrate concentration on rates of an enzyme. The lab was also an opportunity to see a catalyzed reaction

  • Catalysis In Chemistry

    1085 Words  | 5 Pages

    Catalysis is one of the most important phenomena both in nature and chemistry. Photochemistry, which means chemical changes induced by absorption of light, constitutes the basis of human life. Plasmonic nanoparticles are characterized by their well-known surface catalytic properties and strong light-matter interactions.[2] Plasmonic nanoparticles are potentially useful in a number of critical technologies, including solar-to-chemical[1][3][4] and solar-to-electrical energy conversion[5], molecular

  • Activation Energy For The Exergonic Reactions

    1624 Words  | 7 Pages

    the activation energy for the exergonic reactions without a catalysis enzyme is much higher opposed to the reaction with a catalysis enzyme; the free energy is constant and doesn’t change whether if there is a catalysis enzyme; the transition state differs because in an exergonic reaction without a catalysis enzyme, it takes longer for the transition state to occur and has a higher energy peak requirement while if there’s a catalysis enzyme, then the transition state occurs quicker and has a lower

  • Oxidation Of Methane To Methanol Lab Report

    1407 Words  | 6 Pages

    Proposed Mechanisms for the Direct Oxidation of Methane to Methanol The oxidation of CH4 usually progresses to C02 and H20 because the intermediates are a series of highly reactive radical reactions and this makes partial oxidation of CH3 into CH3OH very hard. In addition, CH3OH oxidizes faster than CH4 and requires less energy for its oxidation. Industrial attempts to synthesize methanol from methane is usually done indirectly since the direct methods have low methanol specificity and yield. Current

  • A Summary Of L-Malate

    822 Words  | 4 Pages

    Malic acid, is made by all living organisms. This reaction is catalyzed by the enzyme fumarase, which is also called Fumarate Hydratase. Fumarase catalyzes the trans addition of water to the double bond of fumarate in order to form L-Malate. This catalysis by fumarase is critical for cellular production of energy, which is a part of the citric acid cycle. Most prokaryotes and eukaryotes express two isoforms of fumarase. An isoform is just another name for two or more functionally similar proteins that

  • Questions On Exhaust Gas Recirculation System Essay

    1625 Words  | 7 Pages

    Catalyst X and Y - Reactants Z - Product of the reaction of X and Y In reaction 1 the catalyst is consumed even though in reaction 4 it is subsequently produced, so it does not occur in the overall reaction equation: X + Y → Z 3.4 MATERIALS As catalysis the chemical nature of catalysts is also diverse. For the many reactions involving water, including hydrolysis and its reverse, the most widely used catalysts is proton acids. Multifunctional solids often are catalytically active. e.g. alumina, zeolites

  • Types Of Extreme Temperatures Affect Enzyme Activity

    1225 Words  | 5 Pages

    Observing Enzyme Catalysis Purpose: • Procedure A (Testing Enzyme Activity)- How do different types of extreme temperatures affect enzyme activity? • Procedure B (Establishing a Baseline)- How much peroxide is needed to establish a baseline for a 1.5% solution? • Procedure C (Rate of Hydrogen Peroxide Spontaneous Decomposition)- How do oxygen and water affect the spontaneous decomposition of hydrogen peroxide? • Procedure D (Rate of Hydrogen Peroxide Decomposition by Enzyme Catalysis)-How does different

  • The Effect Of Temperature On Enzyme Activity

    936 Words  | 4 Pages

    means that they begin or accelerate any kind of reaction without being depleted or changed eternally in the process. Enzymes have differing methods but still all produce catalysis by lowering the activation energy for the reaction, which allows it to occur more smoothly. Alteration of temperature can critically modify enzyme catalysis. For example, as the temperature rises the enzyme activity will also increase and will peak at 37-38C. As temperature goes down excessive heat causes the alteration of

  • The Role Catalysts In Chemical Reactions, Their Importance In Industry

    1035 Words  | 5 Pages

    General Certificate Examination - Advanced Level Chemistry (Salters') - Paper 3 mock. ROBERT TAYLOR U6JW. A Catalyst is a substance that alters the rate of a reaction. The catalyst remains unchanged at the end of the reaction. The process is called catalysis. In this report I aim going to explain the role of catalysts in chemical reactions and their importance in industry. I will also outline the problems associated with the use of some catalysts and discuss, using appropriate examples, new developments
