of reaction was much slower‚ and less efficient. The higher the oxygen evolved (gas produced)‚ the more reactions were being produced/higher rate of reaction. Different types of enzymes’ reaction proportions differ based on the pH being added. For example‚ intestinal enzymes may react differently to pH than liver enzymes (catalase) which was tested. The hypothesis was proved to be correct due the rate of reaction increasing as the pH levels got more basic. Based on Graph 1‚ the slope of the pH

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

Task 4 Christopher Mann Student ID: 000458585 June 5‚ 2015 Enzymes are special proteins that carry out chemical reactions‚ also known as catalysts. Two important features that make all enzymes catalysts are their ability to bind to a substrate. A substrate is anything that needs to be changed into something else. The second important feature is that it works to lower the activation energy without being used or changed in the reaction (Hudon-Miller‚ 2012. The breakdown of

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

insoluble fraction called amylopectin [2]‚ which is a branched chain polysaccharide with again α – 1‚4 – glycosidic bonds. At approximately every 25 glucose units‚ a branching of glucose units‚ exists. Upon treatment with acid or under the influence of enzymes‚ the components of starch are hydrolyzed progressively to dextrins (mixture of low melting polysaccharides‚ made up of 3 – 8 glucose units)‚ maltose and finally D-glucose [3]. Starch obtained by animals from plants is stored in the animal body

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
