Sterling Hayden AP Biology Mrs. Proehl 24 November 2014 I. Title Effect of Differing pH‚ Temperature‚ and Enzyme Concentration on Catalase Reaction Rate II. Introduction Enzymes are used to increase the rate of specific reactions in the body. Catalase‚ a specific enzyme‚ speeds the breakdown of hydrogen peroxide‚ a toxic chemical produced by cells in the body‚ into water and oxygen (Cain and others‚ 2010). The oxygen can be observed as bubbles coming from the reaction site. Catalase is found in many living tissues of organisms

Abstract Abstract This practical was designed to investigate the effects of temperature on reactions between the enzyme catalase found in animal tissue with the substrate H2O2. The hypothesis stated that an increase in the temperature of the substrate would create a subsequent increase in the rate of reaction between the enzyme and the substrate. This hypothesis was tested by immersing 1cm cubes of animal tissue (sheep liver) which contained the enzyme catalase into the substrate (H2O2 ) mixed

Case Studies Abstract Alfredo Cano Abstract Innovative methods in language teaching may sometimes be slightly difficult for less experienced teachers. Case studies are a relatively new type of task-based activities for business English students. They have been used in language courses for some time now. It seems‚ however‚ that their full teaching potential has not been used yet. Teachers seem to be uncertain of how to use cases in class.The paper presents the main pedagogical aspects of

Enzymes are biological molecules (proteins) that act as a catalyst and help complex reactions occur everywhere in life‚ for example a piece of steak that is being digested into energy. Molecules found at the beginning of the process are called substrates‚ and these enzymes exchange them into differing molecules known as products. Nearly all-metabolic processes in a cell need enzymes in order to function at rates that are fast enough to sustain existence. Those who are lactose intolerant are simply

Enzymes Ashley Njeru Mrs. Booth Tuesday‚ March 19th 2013 SBI 4U INTRODUCTION: The cellular activity of all organisms is controlled through the use of enzymes. An enzyme is a special type of biological molecule‚ usually a protein‚ which speeds up a chemical reaction; most are soluble in water or a dilute salt solution. There are about 4000 different enzymes in a typical living cell. If even one of these enzymes is missing or

Environmental Parameters of Enzyme Activity Alex Rocha Texas State University Abstract If you’ve ever left a cut up apple out for long‚ you’ll notice that after a while‚ it will turn brown. The reason for this is an enzyme named catechol oxidase‚ a ubiquitous plant enzymes containing a dinuclear copper center (Klabunde‚ Eicken‚ Sacchettini‚ & Krebs‚ 1998). In this experiment‚ we used two different chelators‚ ethylene diamine tetraacetic acid and phenylthiourea to test which would stop
