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

evolved (gas produced)‚ the more reactions were being produced/higher rate of reaction. Different types of enzymes’ reaction proportions differ based on the pH being added. For example‚ intestinal enzymes may react differently to pH than liver enzymes (catalase) which was tested. The hypothesis was proved to be correct due the rate of reaction increasing as the pH levels got more basic. Based on Graph 1‚ the slope of the pH 9 line was more

experiment‚ my lab partners and I tested how time effects a catalase reaction. The amount of hydrogen peroxide was recorded after the reaction for the certain time given has taken place. We used sulfuric acid to stop the reaction with the catalase from occurring. This process is known as denaturing (Campbell 152). The potassium permanganate in this experiment was used as hydrogen peroxide indicator. It determined the amount of hydrogen peroxide remaining after the reaction occurred. Based on our experiment

to the presence of the enzyme catalase. The experiment used two pieces of fish‚ one whole and one ground up‚ which were then covered in hydrogen peroxide. This method allowed us to observe the catalase in ground up fish break down the hydrogen peroxide at a quicker rate than in the piece of fish left intact. This was determined by observing a larger formation of bubbles‚ the visual indicator of hydrogen peroxide being broken down into a non-toxic form of hydrogen and water. This study allowed

that would otherwise be too slow to support life. Catalase is an enzyme present in the cells of plants‚ animals and aerobic (O2 requiring) bacteria. It promotes the conversion of hydrogen peroxide‚ a powerful and potentially harmful oxidizing agent‚ to water and oxygen. Catalase also uses hydrogen peroxide to oxidize toxins including phenols‚ formic acid‚ formaldehyde and alcohols. Catalase is an example of a particularly efficient enzyme. Catalase has one of the highest turnover numbers for all

Rate of Catalase in Various Concentrations of Hydrogen Peroxide QUESTION: How long does the catalase take to float to the top of a cup filled with different amounts of hydrogen peroxide concentration? PREDICTION: A prediction that can be made for this experiment is that the higher the concentration‚ the faster time it takes the catalase to react with the solution. As the concentration increases from 1% to 100%‚ the average reaction rate of the catalase will decrease‚ as the catalase will speed

determining the number of bubbles produce Hydrogen peroxide (H2O2) is a by-product of biochemical metabolism. An accumulation of hydrogen peroxide can be deadly‚ so it has to be decomposed. One of the decomposing factors is an enzyme called Catalase. Catalase breaks hydrogen peroxide into water and oxygen. The chemical formula for the reaction is‚ 2H2O2 2H2O + O2 Since this is a decomposition reaction‚ it is exothermic. Although hydrogen peroxide can gradually degenerate itself‚ it decomposes

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

The Effect of pH on the Rate of Enzyme Catalysis of Catalase Objectives: The objective of this lab was to develop a protocol to investigate the effect of an environmental variable on the catalytic function of an enzyme. More specifically‚ the objective was to perform an experiment in order to test the effect of pH on the function of the enzyme catalase. Introduction: Enzymes are proteins that act as catalysts for reactions. This simply means that enzymes lower the activation energy required
