breakdown of hydrogen peroxide into oxygen and water. The hydrogen peroxide molecule acts as the substrate molecule and enters the active site where it is broke down into oxygen and water. The oxygen and water then leave the active site. Catalase enzyme Hydrogen peroxide (toxic) oxygen + water In the investigation I am doing‚ these are the factors I could change: * The concentration of the enzyme * Increase the temperature * Increase

Devon Backstrom February 5st 2013 PSU Chemistry 222 – Lab 4 Decomposition of Hydrogen Peroxide Abstract: This lab was designed to observe the decomposition of hydrogen peroxide into it oxygen and water. The equation for this reaction is H202 H2O + +1/2O2 thus by measuring volume and pressure of O2 generated the amount of O2 generated can be calculated which in turn can be utilized to determine the concentration of water already in the H2O2 solution. The results determined that 3.02% of the

The actual rate of a chemical reaction however is dependent on two things; the temperature the actual experiment is performed at‚ and the concentration pertaining to the reactants. The rate of a reaction more often

THE EFFECT OF TEMPERATURE ON CATALASE RESEARCH QUESTION: What is the effect of various temperatures‚ 0°C‚ room temperature‚ 37°C‚ 50°C‚ 60°C‚ on the number of oxygen gas bubbles liberated‚ in a decomposition reaction between the enzyme Catalase‚ obtained from crushed mung beans‚ and 2% of the substrate Hydrogen Peroxide? INTRODUCTION: Enzymes are biological catalysts that increase the rate of chemical reactions without they themselves being involved in the reaction itself. Enzymes are proteins

An Investigation on the rate of reaction of the enzyme Catalase on the substrate Hydrogen peroxide. Plan Aim: To investigate the rate of the effect of Catalase on hydrogen peroxide. Introduction This investigation will be carried out to investigate the rate of reaction of the enzyme catalase on the substrate hydrogen peroxide. Enzymes are biological catalysts‚ which speed up the rate of reaction without being used up during the reaction‚ which take place in living organisms. They do this by

investigate the effect of temperature on the enzyme catalase. The original research question was exploring the effect temperature would have on a yeast catalase reacting with hydrogen peroxide (H2O2). To address the latter question a series of experiments were conducted. The various temperatures experimented with were as follows: 22 degrees Celsius (room temperature)‚ 0 degrees Celsius (freezing)‚ 100 degrees Celsius (boiling)‚ and 37 degrees Celsius. Along with variations in temperature‚ the experiment

kind of role does hydrogen peroxide and a liver have in their chemical reaction? In the experiment‚ we saw they had a reaction‚ but completed further tests to determine whether they changed after the reaction. Hydrogen peroxide is chemically changed into water and the liver is broken down in the reaction. In the experiment‚ a fresh piece of chicken liver was put into a test tube filled with 3% hydrogen peroxide. We knew a reaction was taking place because the hydrogen peroxide started to foam and

The Effect of Temperature on the Enzyme Catalase Stephen Francis Biology 183 Abstract This experiment was performed to determine the resultant effect of temperature change on the reaction between the enzyme catalase and hydrogen peroxide. This experiment was performed by measuring and comparing the amount of oxygen bubbles produced and the absorbance of the catalase and hydrogen peroxide solution over time at room temperature‚ 2°C‚ 50°C‚ and 60°C. The overall result of this experiment proved

Nitric Oxide is a gas that helps your body with the circulation of the blood. It also regulates other functions of the body. Nitric Oxide can also help control blood pressure. It is also especially popular with men in that nitric oxide helps with some cases of erectile dysfunction. Nitric Oxide supplements initially became popular with the bodybuilding community. The improved blood flow helps with the "pump" that bodybuilders are always looking for. Making the blood vessels larger allows for better
