EFFECT OF TEMPERATURE ON THE RATE OF CATALASE REACTION IN HYDROGEN PEROXIDE INTRODUCTION Enzymes function similarly to a lock a key mechanism where only one specific key will work (U and Fischer‚ 1994). An enzyme is a macromolecule that acts to increase the rate of either a substrate breaking down into two or more products‚ or where two substrates join up to form one product (Dundon‚ 2018). These enzymes perform this by lowering the activation energy required for the reaction to occur under normal

An investigation to see how much oxygen is given off when different concentrations of catalase are added with hydrogen peroxide. Aim: To see if changing the concentration of catalase (found in celery) with hydrogen peroxide affects the amount of oxygen given of. Background Information: (Hydrogen peroxide - H2O2 1/2O2+H2O) Enzymes: Hundreds of chemical reactions happen simultaneously inside living cells and it’s the job of enzymes to control and regulate the various metabolic

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

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

People need to be informed if work plans need to be changed so that they are aware they need to change what they are doing. It also makes them feel a part in what is going on and get feedback as to whether the plans are workable. Employers are looking at employees who are flexible. It doesn’t mean doing things which you are not trained to do but being organised to help or change what you do to ensure that jobs are finished as soon as possible. The more multi-skilled you become through your experience
