Enzyme Catalase Essay

Enzyme Lab Report Amy (Dohyun Kim)-10I • Research Question: How does pH affect the % of oxygen produced in 1 minutes of enzyme combined with Hydrogen Peroxide (H2O2)? • Independent Variable: Level of pH (vinegar, hydrochloric acid, Ammonia, Sodium hydroxide and water) • Dependent Variable: % of oxygen produced in 1 minute kPa/sec? • Controlled Variables: What is controlled? How are you going to control it? Why do you need to keep it constant? Type/Size of flask Using

Enzyme Lab Conclusion In this lab three hypotheses were tested. If the catalase Solution is added then, the H2O2 will be broken down into harmless byproducts/ there will be an increase in temp compared to the control, if the boiled catalase is added to the H2O2, then there will be no significant increase in temp compared to the control, and if the catalase with acid is added to the H2O2, then there will also be no significant temperature increase compared to the control. The first hypothesis of

Daniel Blinks YR. 11 Background – Catalase are an enzyme that catalyses the reduction of hydrogen peroxide into H2O and O2. Catalase are a common enzyme that can be found in almost all living organisms such as potatoes. It is specifically found in the cells that are exposed to oxygen and can be in a plant or animal cell. [1] The effect of heat above 400 on catalase will make them denature and the production of O2 will slowly decrease. However when the catalase are too cold the rate of O2 production

caused by an enzyme called catalase. Catalase is in most blood and cells, and it should be noted that the enzyme catalase is a catalyst. Catalysts accelerate chemical reactions that otherwise proceed slowly. To put it in different terms, the editors of Encyclopædia Britannica have said that catalase is “an enzyme that brings about (catalyzes) the reaction by which hydrogen peroxide is decomposed to water and oxygen. Found extensively in organisms that live in the presence of oxygen, catalase prevents

1. Enzymes are protein molecules that act as catalysts in chemical reactions. These protein catalysts will speed up biochemical reactions in the body without being consumed in the process. 2. When hydrogen peroxide was added to the liver, a chemical reaction took place. Catalase enzyme in the liver acted as the catalyst in this reaction that decomposed harmful hydrogen peroxide into the safe products, oxygen gas and water. When the reaction occurred, oxygen gas formed bubbles and escaped, while water

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

How does an enzyme affect reaction rates, and how does the acid affect the enzyme itself? In this most recent catalase lab, data both conclusive and inconclusive answered these questions. In the data collected, the major trend was when the hydrogen peroxide concentration (independent variable) increased, the reaction time (dependent variable) of the enzyme decreased. One of the data points did not follow this trend, and will be addressed later. Also, when the acid was added to the enzyme, the reaction

Effects Temperature and Substrate Concentration have on Enzyme Catalase Activity Abstract Enzymes are protein catalysts, which is a substance that speeds up the rate of a chemical reaction. The need of breaking down hydrogen peroxide into oxygen is growing because of the harmful toxins present. In the first experiment we hypothesized that as the substrate concentration increased, so did the reaction rate, therefore allowing more oxygen to be produced is less time. The first experiment mixed each

Introduction: An enzyme is a protein macromolecule which acts as a catalyst, an agent which speeds up reactions without being consumed by it. They are vital to life; cellular chemical reactions would not occur fast enough to support life, without the aid of enzymes. They do this by lowering the activation energy (EA), which is the energy that must be added to the reactants at the start of reactions, it has to be reached in order for the reaction to occur (Reece, Wasserman and Urry). There are hundreds

Introduction The effect different temperatures have on the rate that enzymes work was tested by this lab. The concentration of the enzyme catalase in different tissues was also tested. It was tested by pouring 5 ml of hydrogen peroxide over liver in different conditions and over a piece of meat and potato. Enzymes are balls of protein that change a specific substrate into a product by contact at the active site. Enzymes are reusable and once they finish tuning one substrate into a product, it moves
