Activity of the Enzyme Catalase in breaking down Hydrogen Peroxide and the effect of various factors on Enzyme Activity Introduction The enzyme catalase is present in cells in order to speed the breakdown of hydrogen peroxide (H2O2)‚ which is a toxic chemical to the human body. When hydrogen peroxide is broken down‚ the end products are Water (H2O) and Oxygen (O2). In this report‚ the reaction of catalase to hydrogen peroxide is being tested. Furthermore‚ the effects of temperature‚ concentration

The Effect of Temperature on Enzyme Activity and Oxygen Production Throughout this report you will gain information as to how temperature effects the amount of oxygen produced in an enzyme- catalase experiment. In the experiment we used liver extract as a catalase and created a chemical reaction within a reaction chamber between the catalase and hydrogen peroxide as well as three different controlled temperatures. In the procedure below there will be a step by step process as to how

Lab Ex#8: "Enzymes: Catalysts of Life" INTRODUCTION Enzymes are protein organelles where chemical reactions take place to generate energy within our cells. Without the energy produced from the cell enzyme activity‚ we would not possess the catalyst activity necessary for energy to produce movement. Each enzyme performs a specific function within our bodies. Those functions performed can be significantly altered with the introduction of variables outside their environment. Variables‚ such as temperature

Effect of Temperature on Enzymes ~Abstract~ In this experiment the effect of different types of temperatures on enzyme activity was examined. The temperature baths that were used to test the difference in enzyme activity on fresh liver were; 4 °C‚ room temperature which was 22°C‚ body temperature which is 37°C‚ and 77°C. The total time of each trial was 2 and a half minute‚ 1 minute for the H2O2 to acclimatize to the temperature‚ 1 and a half minutes for the reaction to occur. Catalase causes Hydrogen

INTRODUCTION Enzymes are a protein serving as a catalyst‚ a chemical agent that changes the rate of the reaction without being consumed by the reaction. Enzymes are proteins made up of long chains of amino acids. These form complex shapes. The enzymes are individuals‚ like the different players on a ball team‚ they have different specific structures and jobs. As one ball player may be very tall and one short‚ the specific different shape of the active site on an enzyme is unique and prepares it

Stallings Period 2 January 26‚ 2013 Enzyme Catalysis Lab Report Background: Enzymes are catalyst‚ which affect the rate of a chemical reaction. One consequence includes the cell to carry out complex chemical activities at relatively low temperatures. In these reactions the substrate binds reversibly to the active site. The cause of this is a decrease in the energy needed to activate the reaction of the substrate molecule to from products. Every enzyme is particular for a reaction for the reason

Protocol for Lab 5 – Aerobic Respiration Part 1 Isolation of Mitochondria from Cauliflower - Weigh 50g of rosettes cut from fresh cauliflower head. - Cut rosettes and place it on ice - Prepare juice extractor by placing ice and an empty 150 ml beaker into the right compartment. - Collect pulp from left compartment and record total volume of the extract. Approx. 20ml - Filter the pulp using six layered cheese cloth and collect it in a beaker sitting on ice. - Place two 50 ml test tubes

Lab report April 14‚ 2013 Abstract: In this article‚ we will experiment on the significant in strength of the enzyme by using three different test tubes and measuring the amount of product they give off. To determine this we are going to test the amount of color absorbance by using a special tool to help us understand our results. We will see how our end results show the effect of the amount of concentration we apply to each test tube. The results would be shown by the support of two graphs

LAB 1: What temperature does the enzyme actually work properly in? (Hypothesis) If the temperature is below 40 but above 20‚ then the liver will show bubbles. If the temperature is raised higher than the optimum temperature‚ then an extreme decline in enzyme activity would occur following by the quick denaturing of the enzyme‚ rendering it is permanently useless. Also about 37°C is body temperature. The liver that was at 25°C had a huge amount of bubbles (a 4 on the scale) and the 0°C

Abstract The main goal of the enzyme kinetics experiment was to see how the phosphatase-catalyzed hydrolysis of p-nitrophenyl produced p-nitrophenol in the presence of phosphate and fluoride ion inhibitors of various concentrations. The calculated Km constant was found to be 0.22 for all reactions. The Vmax values for each inhibition ion were 0.00986 for the phosphate ion and 0.00436 for the fluoride ion. The inhibitor constant‚ Ki‚ was determined to be 0.0967 for the phosphate ion. The inhibitor
