Catalase

produced is accompanied by an increase of catalase concentration; though the lower concentrations suffer from slight inconsistencies. This leads to the conclusion that the more enzymes available, the larger and faster the reaction. The data obtained is in agreement with the hypothesis. The hypothesis stated that the rate of reaction and amount of product produced will augment with the increased concentration of the catalase. It was observed that in the 80% catalase concentration the most amount of O2 was produced, while in the 10% catalase concentration the least amount of O2 was produced. The higher ratio of enzyme to substrate…

The purpose of this lab was to find the optimal temperature for the highest efficiency of Catalase. Catalase is a common enzyme almost present in all living organisms and was obtained by extracting the juice out of potatoes in a complex process that could be a lab itself. It was hypothesized that as the temperature was increased the rate at which the Catalase reactions would be speeded up. A 1% solution of Hydrogen Peroxide was placed in the Catalase and the speed at which the reaction…

they become denatured. Denaturation of an enzyme can occur with changes in factors such as temperature, pH, or salinity. The enzyme being used in this experiment is catalase. Catalase is an antioxidant enzyme that helps to…

Studying the reaction of the enzyme catalase in different temperatures The purpose of this experiment was to measure the speed and the effectiveness of the enzyme catalase. The enzyme catalase purpose is to break down harmful substances and turn them into oxygen and water. The substance in this environment was hydrogen peroxide, and the study was to see how well the chicken liver would work if it was in a boiled environment, room temperature environment, an acid immersed environment and a basic…

Abstract: Catalase is an iron porphyrin enzyme present in high concentrations in humans and animals liver tissues. It is a peroxisomal enzyme that is responsible for destruction of toxic H2O2 released during certain metabolic processes.The activity of catalase can be determined by measuring the decrease in H2O2 concentration which is the substrate. Introduction: An enzyme is a large protein that acts as a biological catalyst which changes the rate of a reaction. It provides an active site…

Catalase, is an enzyme where hydrogen peroxide is broken down to water and oxygen ; which causes a response. Found in a lot organisms that live in the surrounding of oxygen, catalase can fend off the buildup and protects cellular organs from damage by peroxide, which is always produced by many reactions. The catalase enzyme is critically important to are health, it can be found in nearly every living organism exposed to oxygen. In the catalase lab we measured the amount of catalase in each…

Catalase containing, positive, bacteria consist of aerobic, oxygen respiring, and facultative anaerobic, can grow either with or without oxygen, bacteria. Being catalase positive means the bacteria is exposed to hydrogen peroxide in a concentration high enough to make it toxic to the bacteria cells. Thus, the cell needs to break down the hydrogen peroxide into water and oxygen gas to survive. Catalase positive bacteria can include beneficial bacteria. Two harmful bacteria that are catalase…

catalysis breaks down hydrogen peroxide into water and oxygen. In this lab we conducted a series of experiment to find the effect of concentration of substrate and the temperature of catalase enzyme. Introduction: There are a lot of factors that can affect the rate of enzyme reaction such as the concentration of the substrate, temperature of the enzyme, and shape of the enzyme. In this experiment we only measure how the concentration of the substrate and temperature of the enzyme affects the…

Discussion Enzymes are biological catalysts that help speed chemical reactions. In part A (table 2), it was seen that a normal reaction of catalase and hydrogen peroxide resulted in the release of bubbles (oxygen gas) and the release of energy in the form of heat which shows that the reaction was a exothermic reaction. The reaction was given a reaction rate of four and acted as the control with which we could compare the other results to. When testing whether or not catalase is reusable in part…

1.)During the lab and based on recorded observations it can be deduced that the enzyme catalase found in potatoes only reacted to hydrogen peroxide. This is do to the fact that before 10 ml of hydrogen peroxide was added to each test tube residing 3 potato samples and the designated liquid, no reaction was observed. Thus demonstrating the catalase's inability to react to vinegar, soda, water, detergent, and Na OH. Furthermore, shortly after the hydrogen peroxide was added to the liquids of…
