Title: Enzyme Catalysis of Hydrogen Peroxide by Catalase Problem and Objectives: How do different temperatures and different levels of pH affect the reaction rate of the enzymes in chicken liver? Demonstrate the activity of an enzyme in living tissue‚ observe the effects of changes in temperature and pH on the activity of an enzyme‚ perform analyses for the presence of an enzyme in tissues‚ and analyzing relationships between environmental conditions and enzyme activity. Background: Cells produce

Catecholase-Catalyzed Reaction Abstract This paper describes an experiment to determine ……………. Introduction Enzymes are made from proteins. They are biological catalysts that speed up the rate of chemical reaction by lowering the activation energy of the reaction. Enzymes are precise and catalyze only detailed reaction. Specificity is an outcome of active site of enzyme that acts on the substrate. Catecholase‚ which catalyzes a reaction in which catechol‚ then catechol becomes the product

bleaches and cleansing wounds. In a cell its build up would be highly toxic. However‚ liver cells contain an enzyme‚ catalase‚ which immediately breaks down hydrogen peroxide. It is a peroxidase and breaks up the toxic hydrogen peroxide to water and oxygen which are both nontoxic. The reaction is exothermic‚ meaning that energy is released in the form of heat. It is the fastest known enzyme. Hydrogen peroxide Water + Oxygen 2H2O2 2H2O O2 List of materials: Safety glasses Iron powder in a watch

Bio 205 Lab W/8:00 Enzyme II Write-Up Methods: My partner and I ran two experiments to measure the activity of the enzyme horseradish peroxidase under varied conditions. The first of which measured the effects of altered pH levels‚ while the goal of the second was to examine the effects of varied temperatures. To test the effects of pH on horseradish peroxidase‚ we began by zeroing a Spec 20 with 5.0mL of substrate (25mM guiacol) at pH 6.5. Once the Spec 20 was accurately zeroed‚ we added 100μL

by pH is the purpose of this experiment. Introduction Enzymes play an important role in daily life because of the chemical reactions. Almost chemical reactions require the presence of enzymes to promote the metabolic process. They are known as the incredibly efficient and highly specific biological catalysts. Most enzymes are protein with the ability to enhance the rate of reaction between molecules. To catalyze a reaction‚ the enzymes have to create the best environment that is called active

metabolism to take place. The digestive system breaks down complicated food particles into molecules (Catabolism) like this: Fat breaks down into Fatty acids by using an enzyme called Lipase. Protein breaks down into Amino Acids by an enzyme called protease. Starch breaks down into sugars by using an enzyme called amylase. These enzymes are produced by hormones. The hormones are activated when you eat. Once we have broken these down‚ we can then build them back up again into a collection of molecules
Premium Metabolism Energy Enzyme
An enzyme is a tertiary globular protein. The function of an enzyme is to lower the activation energy of either the creation or breaking apart of a chemical bond. By lowering the activation energy of this process‚ the reaction of bonding‚ or in this case breaking apart‚ is sped up. An enzyme breaks apart the substrate in the active site of the enzyme; this is where the magic happens. Substrate is what is being broken apart by the enzyme. In this case‚ the enzyme is catalase and the substrate is hydrogen

The effect of varying temperature on thee Rennin enzyme Abstract The purpose of this experiment was to see what affect different temperate had on the reaction rate of the enzyme rennin. The experiment was performed by placing test tubes filled with renin and milk into water bath which was heated or cooled to one of the temperatures trialed. The hypothesis justified because it found because it though data that the enzyme reacted faster with the 45° temperate because it was
