Effect of Catalase at Different Temperatures Abstract The role of this experiment is to determine the effect of temperature on enzymatic activity. The results of the experiment were the colder the temperature the slower the reaction rate and the hotter the temperature the faster the reaction rate. Introduction Enzymes are chemical substances found in living cells and they act as catalysts of the various chemical reactions that occur in them.(Preszler‚ 2012) They bind to substrates that have

General Biology I Spring Semester 2013 Lab Report Name: Date: 03/20/2013 Lab: # Purpose of this lab: To test for the effects of temperature on catalase activity. Introduction: Enzymes are proteins that act as catalysts and help complex reactions to occur everywhere in life. Enzymes affect a chemical reaction by acting as a catalyst‚ which is to say‚ it speeds up the reaction. However‚ extreme ph and temperature hinders enzyme function. Optimal activity of an enzyme

The Cause and Effect of Air Pollution Neidalina Ortiz Everest Online December 28‚ 2013 It would be natural to think that microscopic particles in polluted air would do damage to one ’s lungs‚ nose and throat. However‚ recent research published in Circulation: Journal of the American Heart Association has reported that such particles can in fact negatively affect the ability of the heart in people with serious coronary artery disease to conduct electrical signals

Practical Assessment 2 – The effect of substrate concentration on the rate of enzyme activity of Catalase Aim To investigate the effect of substrate concentration (manipulated by increasing concentration of hydrogen peroxide) on the rate of enzyme activity of catalase‚ produced by liver cells‚ on the decomposition of hydrogen peroxide. Introduction Enzymes are biological catalysts that increase the rates of reactions. In an enzyme-catalyzed reaction‚ the substrate binds to the active site

Research Question This lab will be driven by the research question; do changes in temperature (from 0˚C‚ 7˚C‚ 21˚C‚ 37˚C‚ and 90˚C) have an effect on the activity of the enzyme catalase (found in beef liver) in the breakdown of hydrogen peroxide? Hypothesis If liver is placed in different temperatures of 0˚C‚ 7˚C‚ 21˚C‚ 37˚C‚ and 90˚C and hydrogen peroxide is added to each piece of liver‚ then the liver placed in 37˚C will have the largest reaction height. The liver in 90˚C will have the smallest

form ozone. * Ozone absorbs UV-C or UV-B and most of it will break back down to oxygen. * Ozone has a natural half-life‚ and decays spontaneously with time and temperature back to oxygen. * Ozone encounters water vapor‚ and forms hydrogen peroxide. * Ozone encounters a photocatalyst (like CFC‚ HCFC‚ Halon)‚ and is converted back to oxygen. CFCs‚ HCFCs‚ and Halon: The ozone layer is destroyed by CFC’s‚ chlorofluorocarbons‚ that are used as a propellant in aerosol cans‚ and refrigerants

Executive Summary The recent acquisition of French energy company Alstom by General Electric has made a lot of headlines in the world recently. This is one of the largest acquisitions by the General Electric and involved a lot of complexities. The Alstom’s board of directors was ready to cut the deal with General Electric but French government has made this deal as the national pride and tried to interfere. They opposed this deal on the ground of loss of jobs in France but in reality the French
