    trend O2 production and reaction velocity increased with increasing catalase concentration‚ however‚ the 33% percent catalase concentration showed a drop of 0.175 mL O2/s compared to the 25% catalase concentration (figure 1.2). The velocity of 25% catalase was 0.275 mL/s‚ 33% was 0.1 mL/s‚ 50% was 0.435 mL/s‚ and 75% catalase was 0.575 mL/s (figure 1.1). The 50% catalase concentration produced the most O2 overall however the 75% catalase concentration had the fastest initial reaction velocity. Experiment

    • 4 Pages

    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

    ABSTRACT: This lab allows us to observe the conversion of hydrogen peroxide (H2O2) into water and oxygen gas. An enzyme known as catalase facilitates this decomposition reaction. The catalase enzyme acts as catalysis‚ helping lower the energy needed to activate the reaction while the enzyme itself is not affected. Catalase is a digestive enzyme used to break down hydrogen peroxide‚ which is a normal byproduct of cellular respiration. The reaction could take place without the help of catalase‚ but it would

    affect the optimum operation of enzymes. These condition include temperature‚ enzyme concentration‚ substrate concentration‚ acidity‚ salinity‚ and any present activators/inhibitors. In this particular lab‚ temperature was the environmental factor studied. More specifically‚ the enzyme catalase and its substrate hydrogen peroxide were tested under different temperatures. It was discovered that‚ temperature can affect the optimum operation of enzymes; The enzyme catalase has an optimum operation condition

    Enzymes are biological catalysts or assistants that consist of various types of proteins that work to drive the chemical reaction required for a specific action or nutrient. They can either launch a reaction or speed it up. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS). The catalase used in this experiment will come from five different sources: Spinacia

    until the enzyme reaches its optimum point of saturation‚ after which any increase in the substrate concentration will no longer affect the rate of reaction. The independent variable in this investigation is the varying concentrations of the substrate (Hydrogen Peroxide: 1%‚ 3%‚ 5% and 6%)The dependent variable was the rate of enzyme catalase activity‚ which was measured by the volume of froth produced after one minute.The concentration and volume of liver extract (source of catalase) used was kept

    exercise we studied enzyme catalase‚ which accelerates the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase and measure the rate of activity under different conditions. The laboratory was also conducted in association with a second laboratory that measured the effects of an inhibitor on the enzymes. Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration were the conditions tested in the experiment. Each lab was assigned

    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 conditions. For the enzymes to lower

    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
