    Activity of the Enzyme Catalase in breaking down Hydrogen Peroxide and the effect of various factors on Enzyme Activity Introduction The enzyme catalase is present in cells in order to speed the breakdown of hydrogen peroxide (H2O2)‚ which is a toxic chemical to the human body. When hydrogen peroxide is broken down‚ the end products are Water (H2O) and Oxygen (O2). In this report‚ the reaction of catalase to hydrogen peroxide is being tested. Furthermore‚ the effects of temperature‚ concentration

    Broadly speaking‚ enzymes are proteins that is produced to perform as a biological catalyst in chemical reactions. Catalyst are used to increase the rate of a chemical reaction. In this study‚ we performed two different experiments that investigated the effect of varying substrate concentration‚ and the effect of temperature on the rate of Enzyme-Catalase reaction. In experiment one (i.e. the effect of varying substrate concentration on the rate of enzyme-catalase reaction) we tested the hypothesis

    My topic for the science fair project is "The effect of temperature in energy loss in a basketball". Some of my subtopics for my project include the pressure air and height in a basketball‚ the material a basketball is made out of and the size of the ball. Different sports require different size balls to correspond with the correct bounce it needs to be used during the sport. Thats why you would not be able to use a tennis ball to play basketball because it is too bouncy and a soccer

    Investigation on Effects of Different pH on Enzyme Activity How does the different pH buffers affect activity of potato enzyme/extract? Introduction: Proteins are polymers that are made up of smaller units/monomers called amino acids. There are 20 different types of amino acids‚ thus make up many different combinations in types‚ numbers of amino acids as well as their orders – an explanantion for why there are so many proteins. Every protein‚ due to various reactions of amino acids to each

    My lab group studied the effect of PH on reaction rate/ enzyme activity measured by foam height. PH is the measure of the concentration of hydrogen ions in a solution. The higher the hydrogen ion concentration‚ the lower the pH. Every enzyme has an optimal PH‚ meaning they have a very small window in which they are most active. Our enzyme (potato smoothie) had an optimal PH of 7.0-7.5. We know this because we measured the enzyme’s reaction rate by measuring foam height. The largest foam height we

    Aim: This experiment aims to determine what effect an increase in the surrounding temperature has on the plasma membrane of a typical plant cell structure. Hypothesis: An increase in temperature will damage and denature the plasma membrane and cause the cytoplasm and other substances contained within the membrane to leak out. Introduction: The purpose of a cell membrane is to control the transport of substances moving into and out of a cell. The membrane is an extremely thin layer (8 to 10 manometers

    structure of the enzyme is mainly dependent on the active site and variable groups. Extreme temperatures or extreme pHs can alter the structure of an enzyme. Enzymes function to lower the activation energy to break the bonds. They achieve this by putting stress and pressure on the bonds or creating a microenvironment for the substrate. Enzymes are regulated by inhibitors or activators and can be inhibited by the products of the reaction‚ called feedback inhibition. Enzymes are catalytic proteins;

    lab-Catalase experiment Aim: To investigate enzyme kinetics‚ using different concentration of the enzyme. Hypothesis: The assay system used in the lab consists of a filter paper disc coated with the enzyme and the dropped into a papercup of substrate (Hydrogen Peroxide). As the hydrogen breaks down the hydrogen peroxide into hydrogen and oxygen gas‚ the bubbles of oxygen gas collect underneath the filter and make it rise to the surface of the hydrogen peroxide. The time it takes for the filter to rise

    The Effects of pH‚ TemperatureEnzyme‚ and Substrate Concentrations on Benzoquinone Production BIOL 2051 June 10th 2013 Introduction Enzymes are the ultimate catalysts of living things. Enzymes are made of proteins which are structured and directed by amino acids chains. Enzymes attract and fit substrate molecules to an active site. The active site binds the substrate molecules covalently to enzyme forming an enzyme-substrate complex‚ which catalyzes
