Investigating the Effects Catalyse Has on Hydrogen Peroxide Solution Aim: I am going to investigate the effects which catalyse has on a hydrogen peroxide solution Preliminary work We would use potato to do the experiment because we had done a previous experiment when we put a piece of potato and liver into a hydrogen peroxide solution and the rate of reaction for the liver was too fast to measure and time. But the potato had a slower reaction which will be easier to time and we can
Immobilized Enzymes (Yeast) Abstract Catalase is an enzyme found in living cells and is used to break down peroxides. Yeast cells, which contain catalase, are used to catalyse the decomposition of hydrogen peroxide solution into water and oxygen gas. The yeast cells were immobilized in sodium alginate beads in this experiment. Immobilized enzymes are widely used in biotechnology processes. They can be reused and is more stable at extremes of temperature and pH, thus improves the economy
The Effect of Temperature on the Activity of the Enzyme Catalase Introduction: The catalase is added to hydrogen peroxide (H²0²), a vigorous reaction occurs and oxygen gas is evolved. This experiment investigates the effect of temperature on the rate at which the enzyme works by measuring the amount of oxygen evolved over a period of time. The experiment was carried out varying the temperature and recording the results. It was then repeated but we removed the catalase (potato) and
Investigate: To determine the relationship between surface area and rate of oxygen production when potato tissue is placed in Hydrogen peroxide solution Planning ======== My prediction I predict that the bigger surface area of the potato chips, the faster the rate of reaction of the hydrogen peroxide is being use up and the faster the oxygen is being given off. Also the rate of the oxygen being given off should be directly proportional to each
Catalase and Hydrogen Peroxide Useful info The Enzyme Catalase is a protein molecule which is found in living cells. It is used to speed up reactions in the cells. It is a very specific enzyme and just performs one particular reaction. Catalase is an enzyme found in cells in potatoes and liver and is used for removing Hydrogen Peroxide from the cells. Hydrogen Peroxide is the poison produced during metabolism. Catalase aids the decomposition of Hydrogen Peroxide the by products of which
(H2O2), a colourless liquid usually produced as aqueous solutions of various strengths, used principally for bleaching cotton and other textiles and wood pulp, in the manufacture of other chemicals, as a rocket propellant, and for cosmetic and medicinal purposes. Solutions containing more than about 8 percent hydrogen peroxide are corrosive to the skin. First recognized as a chemical compound in 1818, hydrogen peroxide is the simplest member of the class of s. Of the several processes of manufacture

Analysis of the Decomposition Rate of Hydrogen Peroxide With Catalase As a Catalyst Aim: To measure the rate of decomposition of Hydrogen Peroxide with Catalase from a Yeast solution using PH as a variable. Hypothesis: The enzyme Catalase speeds up the Hydrogen Peroxide decomposition as its active sites match the shape of the Hydrogen Peroxide molecule. This process will only work at certain PH levels as the Enzyme sites may become disfigured at extremes. Logic suggests that Catalase will
Term 1, 2017 Grade 11 Biology In this report we will discuss the rate in which catalase, a type of enzyme, reacts with hydrogen peroxide to create oxygen. We measured the rate that oxygen filled up a glass test tube filled with water, adding more catalase to the hydrogen peroxide to see if oxygen would be made faster. Enzymes are biological molecules that are a catalyst for chemical reactions within cells, they are made out of large proteins. Without enzymes these chemical reactions

Our group developed an experiment to test the rate of reaction of catalase in whole carrots and pinto beans with various concentrations of hydrogen peroxide. Almost all enzymes are proteins and proteins are made up of amino acids. The areas within an enzyme speed up the chemical reactions which are known as the active sites, and are also where the
Comparing the Reaction Rates Between Potato and Hydrogen Peroxide Against Liver and Hydrogen Peroxide Through Loss in Mass Background information: Catalase is an enzyme that is found in all cells. This means that it is an intracellular enzyme. And enzyme is a biological catalyst. A catalyst is some thing that speeds up a reaction without being changed itself. Because of this enzymes and catalysts can be used again and again. Enzymes are protein chains that have a primary, secondary and
hydrogen peroxide solution. The reaction of catalase in hydrogen peroxide solution will change depends on the temperature of the hydrogen peroxide solution. If the reaction time of catalase is related to the temperature of its substrate, when the temperature of hydrogen peroxide reaches to 35-40˚C, the reaction of the catalase will be the fastest which means it consumes the least amount of time for the reaction. The independent variable in this experiment is the temperature of hydrogen peroxide solutions
