Introduction
In this lab, we ar going to demonstrate that temperature is a factor that has an affect on the speed of enzyme-mediated reactions. The enzyme we will be using is c whollyed catalase. Catalase was the first enzyme to be discovered and, for a long time, was thought to be the solely enzyme in cells. Thousands of specific enzymes, however, have been described since those early days. Catalase speeds the equipment failure of hydrogen peroxide into water and group O. Therefore, as hydrogen peroxide is broken down, you will observe bubbles of oxygen forming.
Catalase enzymes, like all other enzymes, ar protein macromolecules composed of many specific amino group acid molecules. In addition to converting hydrogen peroxide to water, catalases sewer oxidize various toxic organic chemicals like phenols. These enzymes fortune a space within cells in a compartment called a peroxisome, which contains enzymes important for lipid metabolism and for the decomposition of dangerous oxygen compounds like hydrogen peroxide. The primary function of catalase enzymes is the rapid breakdown of hydrogen peroxide into water and safe oxygen compounds. some metabolic pathways in organisms produce hydrogen peroxide as a by-product of other chemical reactions.
If it were left in living tissues, this could cause extensive cellular damage that would cursorily endanger the organism if peroxide accumulation continued unchecked. For this reason, catalase enzymes are necessary parts of normal cellular equipment. Catalase is found in the vast majority of living cells and nearly every aerobiotic cell.
My hypothesis is that the reaction rate will be the hurried when the temperature is at 37C, and very high temperature - boiling - will change the enzymes, and therefore no reaction will occur. I presuppose that the enzymes will denature after 40C and any other temperature to a higher place that. Reason being that enzymes are proteins and their structure is...If you want to loaf a full essay, order it on our website: Orderessay
