The Catalase Test Why Do You Need To Be Careful Not To Jostle The Vp Tube While Waiting For The Results To Show

Catalase Lab Introduction: Catalase is an enzyme normally found in many plant and animal tissues. Its purpose is to destroy toxic substances which may be introduced into cells. Also, some cells use catalase to destroy cellular debris or worn out organelles. In this lab, we will use a catalase solution from potatoes and determine the effect of temperature and pH on the action of this enzyme. The substrate of the enzyme will be 3% hydrogen peroxide (H2O2). Catalase works by the following mechanism: ...

Catalase Enzyme Detection

Title: Catalase enzyme detection Objective: To understand the function of catalase in cells that produce the enzyme, interpret the results of a catalase test and know their value in differentiating bacteria. Materials: 1 clean microscopic slide, 3% H2O2 solution, swabs. Micrococcus luteus, Enterococcus faecalis, patient G Procedure: 1) Scrape some cells off from each bateria to the slant and place them on glass slide. 2) Place one or two drops of H2O2. Watch for bubbling as an indication of...

Effect of Temperature on Catalase

reaction between Catalase and H2O2 Sarah AlShemesi In this experiment we’ll be exploring the effects of temperature on the reaction between Catalase and H2O2.We’ll be using five different temperatures to test this. The five different temperatures will be 10, 30, 50, 70 and 90 oC. We will use the liver as a source of Catalase. A 1 gram piece of liver will be inserted into a test tube with 2 cm3 of water, then 2 cm3 of H2O2 will be added. The Catalase and H2O2 are expected to react and result in bubbles...

An Investigationinto the Effect of Ph on the Activity of Potato Tissue Catalase

An Investigation Into The Effect Of PH On The Activity Of Potato Tissue Catalase Aim The aim of my investigation is to see how pH affects the activity of potato tissue catalase, during the decomposition of hydrogen peroxide to produce water and oxygen. Catalase + 2H2O2 Catalase + 2H2O +O2 Catalase + Hydrogen Peroxide Catalase + Water + Oxygen Independent Variable The independent variable in this investigation is pH. Each individual enzyme has it’s own pH...

Enzymes Test for Effect of pH on Catalase Activity

College General Biology I Enzymes, test for effect of pH on catalase activity Purpose The main purpose of this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids, which are made from proteins. In order to make an enzyme, hundreds of amino acids are strung together in a very specific and unique order and eventually is folded...

Catalase Enzyme Lab

Catalase Enzyme Lab Samiya Hussein March 9, 2012 Introduction In order to receive the necessary amounts of energy required for daily function, the digestive system must break down proteins, fats and carbohydrates. In doing so, the body produces poisonous chemicals; however, the cells aren’t harmed. This is because enzymes are used to break down these chemicals. The name of the enzyme that was the main focus of the lab is catalase. Catalase is responsible for catalyzing hydrogen peroxide...

Catalase Lab Report

enzyme; this is where the magic happens. Substrate is what is being broken apart by the enzyme. In this case, the enzyme is catalase and the substrate is hydrogen peroxide, or 2H2O2. As the catalase and the substrate interact, the substrate is brought into the catalase and broken apart into water and oxygen. This process may be able to happen naturally, but the enzyme, catalase, speeds up the process. It does so by bringing a molecule into it's active site and shifting it's own shape to put strain...

Simple experiments on The enzyme Catalase

Simple Experiments on the Enzyme Catalase Aim: The aim of this practical is to use three different techniques to investigate the effect of different concentrations of the enzyme catalase on the rate of breakdown of hydrogen peroxide. Background information Catalase is an enzyme which is found in all living organisms. This enzyme catalases the decomposition of hydrogen peroxide into water and oxygen. Cells continually produce a poisonous by-product of metabolising, called hydrogen peroxide. ...

Why I must Be Careful

Why I Must Be More Careful By Freddie L. Holmes Jr As I sit and type, while I can think of a million reasons why I need to be more careful and not speed, there are two reasons that seem to stick out at the top of my head. The first reason is, I need to be more careful because I could cause harm to myself and second, and more importantly, to someone else. Causing harm to me can lead to a whole lot of heartache for my family. It would further prove that everything my Mom and Dad were telling...
