experiment. Catalase to be more specific which is found in the liver. We will compare its action under different conditions with an inorganic catalyst called manganese dioxide. Purpose The purpose of performing this lab is to compare the action of catalase to a non-protein catalyst under different conditions. Hypothesis In section A‚ I hypothesize that the sand will have no reaction but the MnO2 will produce a gas or start to foam up. In section B‚ I suspect that the liver may start

Function of Catalase Rena Mototani Problem: How does the pH of a cell affect the function of the enzyme catalase? Introduction In this lab‚ we experimented the effects of pH on the function of the enzyme catalase. Catalase is an enzyme that brings about the reaction by which hydrogen peroxide is decomposed to water and oxygen (Encyclopedia Britannica). The chemical reaction is shown as 2H2O2 = 2H2O + O2 (Keilin and Hartree 397). The reaction involves primarily the adsorption of hydrogen peroxide at the

Part B: Practical Report The Effect of Temperature on Enzyme Activity Aim: To investigate how temperature effects the enzyme catalase. Hypothesis: If the temperature of water is increased then the enzyme will react quicker to form oxygen and water‚ when compared to cold water. Purpose: To design and conduct a plan of a practical about the effects of temperature on enzymatic activity with a partner. Introduction: An enzyme is a protein‚ which speeds up a specific chemical reaction without altering

Research Question Does the concentration of substrate (H2O2 (hydrogen peroxide)) have an effect on the activity of the enzyme (catalase)? Theory The higher the substrate concentration the more quickly product is produced (rate of reaction increases) until enzyme saturation is reached at which time more substrate has no further effect. Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all

designed to investigate the effects of temperature on reactions between the enzyme catalase found in animal tissue with the substrate H2O2. The hypothesis stated that an increase in the temperature of the substrate would create a subsequent increase in the rate of reaction between the enzyme and the substrate. This hypothesis was tested by immersing 1cm cubes of animal tissue (sheep liver) which contained the enzyme catalase into the substrate (H2O2 ) mixed with detergent which foamed showing a visual

which need to be converted. The liver produces hydrogen peroxide‚ which is extremely poisonous. When the catalase comes in contact with the hydrogen peroxide‚ it is broken down into water and oxygen. Aim: The aim is to investigate and determine the effect of change in pH on the activity of the enzymes catalase.

change its own shape‚ which makes enzymes different from other proteins. A common enzyme that we have is catalase‚ which breaks down hydrogen peroxide into the products water and oxygen. To observe this catalase activity I used small amounts of liver samples slightly smaller than the size of a pea to see the reaction when hydrogen peroxide is added to it. In this experiment I exposed the liver samples in three different temperature environments: 3°c‚ 22°c‚ and 75°c. I wanted to measure how much
