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

Catalase Enzyme Lab Samiya Hussein March 9‚ 2012 Introduction In order to receive the necessary amounts of energy required for daily function‚ the digestive system must break down proteins‚ fats and carbohydrates. In doing so‚ the body produces poisonous chemicals; however‚ the cells aren’t harmed. This is because enzymes are used to break down these chemicals. The name of the enzyme that was the main focus of the lab is catalase. Catalase is responsible for catalyzing hydrogen peroxide

Enzymes are biological catalysts that operate at the temperatures‚ pressures‚ and moderate pH values found in living organisms. They help in a faster chemical reaction in our human body. Besides this‚ enzymes also play a huge role in various industries. The following paragraphs will talk about how various enzymes are used in various industries : The Dairy Industry and Medical Industry. In the dairy industry‚ the enzyme Protease is used widely. While making cheese‚ protease helps coagulate milk

____________________ Immobilizing an enzyme provides various analytical benefits‚ and can be done in a myriad of ways‚ with the most common being entrapment. For this study peroxidase (from horseradish)‚ an enzyme that catalyzes the cleavage of hydrogen peroxide into water‚ was entrapped within a polyacrylamide gel matrix. The gel matrix was formed by the addition of methylene bis-acrylamide (a cross linking agent) to acrylamide. The immobilized enzyme was then tested via spectrophotometric assay
