Introduction: Catalase is an enzyme‚ which is present in all life forms that utilize oxygen for their biological processes. Enzymes are proteins which increase the rate of reaction by decreasing the activation energy (the energy required to initiate a reaction). One of the main function of Catalase is to prevent the accumulation of hydrogen peroxide (H2O2) in the body by breaking it down into water and oxygen gas. Hydrogen peroxide is a toxic by-product of metabolic reactions. If hydrogen peroxide

Catalase is a common enzyme found in the bodies of all living organisms in contact with oxygen. It is involved in reacting with hydrogen peroxide to convert it into water and oxygen and can do so with millions of hydrogen peroxide particles each second. These types of enzymes have many uses in bodily systems commonly known as proteins that speed up the rate of the metabolic process by regulating the chemical process which helps digest food and break down toxic substances. The most favourable conditions

In this experiment we are trying to determine the effect temperature has on catalase activity. We started out with five test tubes and then labeled them as we went about‚ after we added a catalase extract to each tube. Once added to each test tube they all sat in their respected temperature for ten minutes‚ so they could have a full effect. Once the time was up each was then collected and then we began to shake them from side to side for the foaming to start. When the foam settled‚ we discovered

the bacterium was a gram negative or a gram positive. After performing the gram stain‚ I concluded that by the appearance of purple spherical clusters resembling grapes that is was a gram positive cocci. A Catalase test was then performed using hydrogen peroxide. A positive catalase test was observed when bubbles started to form on the culture distinguishing Staphylococcus spp. form on the culture distinguishing Staphylococcus spp. from Streptococcus spp. Finally‚ a Mannitol Salt Agar

Enzyme is a type of protein that speed up the rate of reaction of living organisms. Enzyme also acts as a catalyst for specific chemical reaction by converting a specific reactants into a specific product. The enzyme activity will also be affected by temperature and pH value. In this experiment‚ enzyme was placed in carbohydrate solution at different temperature to identify unknown carbohydrate solution. The enzyme that involved in the reaction is salivary amylase. The action of amylase on starch

EFFECT OF TEMPERATURE ON THE RATE OF CATALASE REACTION IN HYDROGEN PEROXIDE INTRODUCTION Enzymes function similarly to a lock a key mechanism where only one specific key will work (U and Fischer‚ 1994). An enzyme is a macromolecule that acts to increase the rate of either a substrate breaking down into two or more products‚ or where two substrates join up to form one product (Dundon‚ 2018). These enzymes perform this by lowering the activation energy required for the reaction to occur under normal

decreasing the energy of activation. The main function of enzyme catalase is to convert hydrogen peroxide (H2O2) in our bodies into oxygen and water. This can be visually seen when hydrogen peroxide is put on a wound and the peroxide bubbles. Enzymes can also be found in plant cells and fungi. (Huston.) In this experiment we test the many variables that can change the rate of this reaction such as temperature‚ concentration levels of enzyme catalase and pH values. We are able to track these changes using

Our computer facilities intends only into a very limited units so that our Lab supervisor easily maintain and create schedules for students who has a computer subjects. By this time‚ Speed Computer College again increased by staggering a percent of two hundred enrollees. One of the main problems of Speed Computer College

experiment was the enzyme‚ catalase. An enzyme is a specialized protein which catalyzes reactions in cells. The enzyme in our experiment was catalase‚ which came from the potato juice. The function of an enzyme is to catalyze reactions in cells. The specific function of the enzyme in this experiment was to see if it affected the activity if it was exposed to different temperatures. A substrate is a material or substance which the enzyme acts. The substrate in our lab was hydrogen peroxide.
