    of the factors that affect the enzyme activity will be examined. All enzymes are proteins. The function of enzymes are to accelerate defined chemical reactions by alternating the rate of the reaction. They will not trigger a reaction to take place that would not occur naturally. Having a particular enzyme to catalyze each of the chemical reactions that take place in a living cell, total control of metabolism can be sustained by an organism. Catalase is an enzyme found in cellular organelles called

  • Enzyme Reaction Essay

    rate of reaction of the enzyme? Background information: Catalysis is the increase in the rates of chemical reactions due to the participation of catalysts. Catalysts are substances that cause catalysis. An example of this is enzymes. Enzymes are proteins that speed up the rate of a chemical reaction of substrates. The substrates will be broken down or turn into products with the aid of enzymes. Enzymes and substrates are often said to fit like a “lock and key model” because each enzyme has exactly

  • The Rate of Reaction of an Enzyme

    399 Words  | 2 Pages

    The Rate of Reaction of an Enzyme Prediction I think that as the temperature raises the rate of reaction will be quicker, until it gets to a certain temperature where the enzyme becomes denatured. The reasons why I believe that this will happen are due to my background research and also to my knowledge of particle theory. When a substance is heated the particles in that substance gain kinetic energy and move around more. This means that the particles collide more

  • Enzyme Reactions and Temperature

    Enzyme Reactions and Temperature Purpose Aim - To determine the effect of temperature on the rate of reaction of rennin when it reacts with milk to cause coagulation. Hypothesis - As rennin is naturally found in the human stomach I believe that the optimal temperature for reaction will be approximately 37°C as this is the regular human body temperature. This is shown by the graph below. [IMAGE][1] Background Research Rennin is "an enzyme that catalyses

  • Rate of Reaction Using Enzymes

    Rate of Reaction Using Enzymes In this bit of coursework I will be investigating the rate of reaction in which enzymes are the catalyst breaking down a substrate. The substrate I am going to use is Hydrogen Peroxide (H2O2, water with another Oxygen), this molecule usually breaks down on its own accord, but also the rate of decomposition can be increased with the use of a catalyst; in this case the catalyst is a biological one called an enzyme. Hydrogen Peroxide

  • Investigating Enzyme Substrate Reactions

    Investigating Enzyme Substrate Reactions Aim: To devise an experiment which will give greater understanding about enzyme catalysed reactions. Background Information Hydrogen peroxide (H2O2) is a powerful oxidant; it readily breaks down into water and oxygen. The breakdown can be speeded up by introducing the enzyme, oxidoreductase (commonly known as catalase). [IMAGE] I will investigate the effect of varying hydrogen peroxide concentrations on the rate

  • Biochemical Reactions and Enzyme Kinetics

    1663 Words  | 7 Pages

    Enzyme Kinetics Enzymes are described as the organic catalysts, which increase the rate of reaction of a biochemical reaction. Enzymes are proteins that speed up the rate of reaction without being used up, and therefore they are reusable (Jonathan, 2012). The enzyme studied in this lab was succinate dehydrogenase. Enzyme kinetics is the study of how biological catalysts increase the reaction rate in reactions. Without the catalysts, the biological procedures necessary for organisms would not continue

  • Temperature and its Effect in Enzyme Catalyzed Reactions

    557 Words  | 3 Pages

    Enzyme Catalyzed Reactions – How does temperature affect its rate? Catalase is one of the most potent catalysts known. It is an extraordinary enzyme. It is ubiquitous, it is found in animal and in plant cells. It catalyzes crucial reactions involving H2O2, with extreme efficiency. The reactions it catalyzes are crucial to life. Catalase catalyzes conversion of Hydrogen Peroxide, a powerful and potentially harmful oxidizing agent, to water and molecular oxygen. Catalase also uses Hydrogen Peroxide

  • Following the Progress of an Enzyme Controlled Reaction

    an Enzyme Controlled Reaction Plan ---- Enzymes are a widely used source of biological catalyst; they are used in widely in industry as in the biological aspects. Enzymes are biological catalyst; this means that they will speed up a reaction with out becoming used up. The enzymes for this by not actually interfering with the reaction its self but basically align the two substrates on the active site of the enzyme. Amylases are widely spread enzymes that

  • How Temperature Affects Enzyme Reactions

    793 Words  | 4 Pages

    How Temperature Affects Enzyme Reactions I am planning to perform an experiment to find out how and if temperature affects the rate of which enzyme reacts. The enzyme I will be using will be amylase. Amylase is an enzyme that breaks down starch so we will test at what temperature the amylase will break down the starch at the quickest time, therefore looking for the enzymes’ optimum temperature, at a temperature lower than the unknown optimum the amylase will work slower
