    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

  • The Enzyme Catalase Experiment

    1751 Words  | 8 Pages

    The Enzyme Catalase Experiment Aim A series of experiments involving the enzyme Catalase has been performed in order to determine some of the enzyme's properties. The enzyme had its reaction rate found in different conditions. Variation of enzyme concentration, variation of pH, variation of temperature, and the effect of different concentrations of inhibitors were all tested. Increasing the enzyme concentration increased the reaction rate. An optimum pH and temperature were found for

  • Enzyme Activity in the Catalase

    1803 Words  | 8 Pages

    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

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

    1594 Words  | 7 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

  • The Effect Of Enzyme Experiment On Catalase Concentration

    1613 Words  | 7 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

  • Activity of the Enzyme Catalase with Hydrogen Peroxide

    2153 Words  | 9 Pages

    Activity of the Enzyme Catalase with Hydrogen Peroxide Background Information: An enzyme (Catalase) is a biological catalyst. It can modify the rate of reaction without being changed itself. Enzymes are also globular proteins that have a three-dimensional specific shape; among with a pocket known as the active site, this has a precise shape to link with the exact substrate. Every enzyme are capable of converting one kind of substrate molecule into one kind of product molecule, which forms

  • An Investigation Into The Rate of Reaction of The Catalase Enzyme

    866 Words  | 4 Pages

    Into The Rate of Reaction of The Catalase Enzyme Introduction: In this experiment I will attempt to investigate the factors that effect the rate of reaction of the catalyse enzyme. Catalyse is an enzyme found in food such as potato and liver. It is used for removing hydrogen peroxide because of the shape of the hydrogen peroxide molecule; this type of reaction is when a molecule Is broken down into smaller pieces called catabolic reaction. Enzymes are proteins e.g. catalyse. They

  • The Effect Of Substrate Concentration On The Activity Of The Enzyme Catalase

    The Effect Of Substrate Concentration On The Activity Of The Enzyme Catalase A Level Biology Project Aims This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Introduction This is a real A-level school project and as such is intended for educational or research purposes only. Extracts of this project must not be included in any projects that you submit for marking. Doing this could lead to being

  • The Effect of Substrate Concentration on the Rate of Activity of the Enzyme Catalase

    3145 Words  | 13 Pages

    Concentration on the Rate of Activity of the Enzyme Catalase Background Information: Enzymes are biological catalysts that increase the speed of chemical reactions without undergoing any physical change. They are neither used up in the reaction nor do they appear as reaction products. All enzyme catalysed reactions are reversible. Enzymes effectively lower the amount of activation energy required for chemical reactions to start. Some enzymes weaken covalent bonds within the substrate

  • Investigation of How the Concentration of Catalase Enzyme Affects the Rate of Reaction

    1136 Words  | 5 Pages

    Investigation of How the Concentration of Catalase Enzyme Affects the Rate of Reaction Aim: To find out how the concentration of Catalase Enzyme will affect the enzyme activity and the rate of reaction towards Hydrogen Peroxide. (H O ) Prediction: I predict that with the higher concentration of enzyme, the likelihood of it breaking down molecules will be greater because there will be more enzymes to work at the substrate and the chances of it colliding will be higher making the activity
