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 into oxygen and water. Since hydrogen peroxide is continuously produced by numerous metabolic reactions‚ catalase helps to prevent the body tissues from being damaged by the peroxide. pH is used to measure the acidity or basicity of a solution and is very important when chemical reactions are concerned.

nourishment. In this case it is hydrogen peroxide. This lab report will be explaining the experiment held to understand the effects of the changes in the amount of substrate on the enzyme’s reaction. Research question: What does the changes in the amount of substrate on an enzyme’s reaction effect on? Hypothesis: I forecast that the more concentrated the hydrogen peroxide is the higher the volume of the foam is and the less concentrated the hydrogen peroxide is the lower the volume of the

Concentration of Hydrogen Peroxide on the change in reaction rate of liver catalase. Hypothesis: Null Hypothesis: If the concentration of the Hydrogen Peroxide is changed then there would be no change in the reaction rate. Alternate Hypothesis 1: I there is an increase in concentration in concentration of Hydrogen Peroxide then the reaction rate of the liver catalase will increase. Alternate Hypothesis 2: If there is an increase in concentration in concentration of Hydrogen Peroxide then the reaction

affect the distribution of hydrogen peroxide by the catalase in this organism. In this catalase and hydrogen peroxide experiment‚ we will find out how enzymes act as catalysts by causing chemical reactions to occur. Using a potato and hydrogen peroxide‚ we can observe how enzymes like catalase work to perform the breaking down‚ of other substances. We will look at enzymes and catalase and its substrate hydrogen peroxide. Catalase accelerates the breakdown of hydrogen peroxide (H2O2) into water

Practical Report: Background Information: Hydrogen peroxide (H2O2) is a combination of hydrogen and oxygen. In high concentrations‚ it can be unstable and even poisonous. In lower concentrations‚ such as the types found in many homes‚ it works well as a disinfectant and antiseptic.The reason behind foaming of Hydrogen peroxide is because blood and cells contain an enzyme called catalase. Since a cut or scrape contains both blood and damaged cells‚ there is lots of catalase floating around.When

Abstract: Enzymes‚ molecules that speed up chemical reactions‚ are specific to one substrate. In this experiment the substrate hydrogen peroxide and the enzyme catalase will be used. The higher the concentration of potato extract‚ or catalase‚ the faster the reaction and the more substrate present will result in a decrease in the time of the reaction. The amount of concentrations of enzymes and substrates are changed to determine if the reaction is further catalyzed by a greater concentration of

14th-15th October Title: The effect of the concentration of hydrogen peroxide on catalase Aim: to examine how the concentration of the hydrogen peroxide affects the rate of reaction Hypothesis: The substrate concentration will determine the rate of reaction. The reaction will increase as the concentration increases‚ but from a certain concentration‚ the rate will maintain the same rate Materials: 3% hydrogen peroxide 6% hydrogen peroxide catalase round metal basin measuring cylinder thermometer

concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information 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 very specific as each enzyme just performs one particular reaction. Catalase is an enzyme found in food such as potato and liver. It is used for removing Hydrogen Peroxide from the cells. Hydrogen Peroxide is the poisonous by-product
