Enzyme Catalase Essay

The catalase enzyme is so critical to our health that it is found in nearly every living organism on the planet that is exposed to oxygen. This antioxidant enzyme can catalyze the conversion of hydrogen peroxide into water and oxygen. Hydrogen peroxide is a by-product of cell metabolism, which serves some useful functions including healthy immune response. (Group, 2013) Catalase has one of the highest rates of turnover when compared to all other enzymes. In other words, one catalase enzyme can change

was to discover the exact change of enzyme activity of catalase and how it corresponded to temperatures, by measuring the rate of appearance of a product. Introduction: Enzymes are substances produced by living organisms, in which act as a catalyst. Their purpose is to trigger a specific biochemical reaction, and provide control of metabolism. Enzymes lower energy barriers, which is why they are able to increase the speed of a cell's chemical reaction. All enzymes are considered protein macromolecules

Catalase Enzyme Lab Introduction The human body is an incredible system that is capable of working a multitude of diverse functions. Without the help of the many different protein molecules, the human body would not be able to function properly. One major group of proteins called enzymes are mandatory for essential life. These proteins are constantly at work assembling molecules, metabolizing energy, and fighting off infections. An enzyme is a macromolecule that acts as a catalyst that

Organisms use enzymes in order to break down potentially harmful materials in the body and to carry out chemical reactions. One such process that involves substances and enzymes in the body is processing H2O2 by the liver and other body systems into water and oxygen. In an enzyme catalysis lab, the goal was to find out how, as time passes, how much H2O2 will be left over after reacting with the enzyme catalase. Samples from various times were used in order to stop the catalysis sulfuric acid (H2SO4)

Methods Part I: Using Banana to determine the Decomposition of Hydrogen Peroxide with the Enzyme Catalase In order to establish the basis of the reaction, an oxygen gas collector would be setup for the collection of oxygen gas that would be released in each stage of the reaction. First, two test tubes were labeled test tubes W for the whole banana and test tube D for the diced banana. 5 ml of 3% hydrogen peroxide with the PH of 7.0 was added into two test tubes W and D. Observations of the hydrogen

effects of temperature on catalase enzymes. Introduction: Enzymes are defined as being molecules that function as biological catalysts, increasing the rate of reaction without being consumed by the reaction. They allow molecules to use less energy to create the reaction. Each enzyme has a specific shape for its substrate and only that substrate can bind to the enzyme to create the reaction. If environmental factors change such as PH levels or temperature this could cause enzymes to change their shape

our lab, we tested how enzymes and substrates work and react together. An enzyme is a protein that acts as an organic catalyst and lowers the activation energy needed to start a chemical reaction. Each enzyme has only one specific job and is reusable. Enzyme action begins when the substrate fits into the active site of an enzyme, and from there the enzyme can further break down the substrate by putting stress on it, causing the bond to break. In our lab, we used catalase that was found in liver

Purpose: The purpose of this lab is to test the enzyme catalase to see if adding more enzymes speeds up the reaction and, we will test it with pH and different temperatures. Also, I will be using potato juice as a catalase and measuring the amount of bubbles you get when you mix it with hydrogen peroxide. Procedure: Experiment 1: Enzyme- Substrate Specificity Obtain 3 test tubes and fill them up to 1 cm with potato juice and 5 cm with the hydrogen peroxide. After filling up the tubes swirl

this experiment was to record catalase enzyme activity with different temperatures and substrate concentrations. It was hypothesized that, until all active sites were bound, as the substrate concentration increased, the reaction rate would increase. The first experiment consisted of five different substrate concentrations, 0.8%, 0.4%, 0.2%, 0.1%, and 0% H2O2. The second experiment was completed using 0.8% substrate concentration and four different temperatures of enzymes ranging from cold to boiled

an enzyme. An enzyme is an organic catalyst that speeds up the rate of a chemical reaction without being consumed by the reaction. Enzymes are proteins, meaning that they have a unique structure that dictates what their function is. This unique structure also determines what substrate, or specific reactant, the enzyme will catalyze. From there, the substrate and enzyme bind together; which leads to the reactants being created. The enzyme tested during this experiment was the enzyme catalase. This
