was to find out at which level of pH the enzyme catalase would produce the highest amount of oxygen while it was breaking down the hydrogen peroxide. The hypothesis which was formed by the experimenter states that if the pH of cow liver is lowered by different amounts of hydrochloric acids, varying from 0 drops, 5 drops, 10 drops, 15 drops, and 20 drops, then the amount of oxygen that is produced from the catalase enzyme suspension would be the greatest when the pH of the cow liver is at its highest
hydrogen peroxide to figure out the reaction rate for the enzyme catalase in that specimen. There were four different parts to this experiment. Part A consisted of Observing Normal Catalase Reactions. Part B was What Tissues Contain Catalase and Part C was titled What is the Effect of Temperature on Catalase Activity? And our final part was Part D and we found What is the Effect of pH on Catalase Activity. In Part A, Observe Normal Catalase Reaction, we discovered that when we put the liver in the hydrogen
had four different parts each testing different things. In each part of the lab we tested different things about catalase. We studied the enzyme found in many cells from many living things. The catalase speeds up reactions and breaks down hydrogen periodic into harmless substances. Though every test done we estimated what we thought the rate of reaction was from (1-5) based on what we observed. Part A, the first part to the lab, we tested three different things. The reaction of normal liver and
The effects on rate of reaction of enzymes when changes in temperature, pH and enzyme concentration occur Abstract The purpose of this lab was to test the effect a change in temperature, pH and enzyme concentration has on the rate of reaction of enzymes. The enzyme being studied is known as catalase, and it is used to speed up the reaction that breaks down hydrogen peroxide into water and oxygen. Using enzyme rich liver and reacting it with solutions of various temperatures, pH, and concentrations
The Effects of pH Levels on Catalysts Samantha Burns September 29, 2015 Mr. Lau Abstract This lab’s purpose is to demonstrate the effect of pH on the catalase enzyme found in liver peroxisomes. It is hypothesised that if the pH level rises, then the rate of reaction will become faster. This will be determined by reacting hydrogen peroxide with liver peroxisomes in three different tubes with varying pH levels. The major findings from this laboratory were: The bubbles grew at a rate of about
Earlier, it was stated in the hypothesis for Part A that if the pH level was too acidic or too basic, then the reactivity and reaction rate of which the catalase breaks down hydrogen peroxide will decrease. The hypothesis was true. There was no reaction when hydrogen peroxide was added to water because there were no catalase to break down the hydrogen peroxide. When H₂O₂, hydrogen peroxide, was added to the liver puree in test tube 1, 2 millimeters of bubbles were formed. When H₂O₂ was added to the
Introduction: Purpose (Parts 1-5): To describe how enzymes work using molecular models. To experimentally test the enzyme catalase in liver cells with hydrogen peroxide and identify the type of reaction occurring. To determine which types of tissue respond and react with catalase. To discover how the change in temperature affects enzyme (catalase) activity. To observe the effects of pH on enzymes. Background: In this lab, liver, muscle tissue, apple, carrot, and potato were used to examine the reaction
Outside Effects on the Rate of Reaction of the Catalase Enzyme By: Capria M Davis Bio 125A Lab 11am-1:50pm Dr. Erin Mulholland 10-28-14 Abstract In this experiment, the rate of reaction of a catalyzed enzyme is being tested under three different controlled variable circumstances. These variables include the amount of enzyme used, temperature as well as pH level. This is important because it allows us to look at how enzymes react when put under different conditions. This
Abstract: Catalase speed up reaction rates in substance or even molecules. Factors such as temperature and substrate concentration can also contribute the speeding up of reaction rates. Previous research has shown how these factors influence the reaction time of particular substances. This is most likely because catalase speeds up reactions along with the contributing factors, making the reaction happen much quicker. In our experiment, we tested five different substrates (0.8%, 0.4%, 0.2%, 0.1%
examined by the enzyme catalysis which was yeast. The enzyme catalase was placed in 4 different test tubes that contain different factors that would determine if the factors affected the enzyme reaction. To demonstrate the effects of temperature on the change of the enzyme reaction, 2ml of yeast solution was placed into a test tube that contained 1ml of 1% hydrogen peroxide. . Due to the test tube not being heated up the reaction between the catalase and the hydrogen peroxide was slower than expected. If
