Wan Ching Man 5C(21) Effects of temperature on the activity of lipase Aim: To investigate the effects of temperature on the activity of lipase enzyme on milk which contain fats or lipids. Introduction: Enzyme is a kind of biological catalyst that made up of protein. It can speed up the metabolic reactions on various kinds of substances. Like lipase can break down lipid into glycerol or fatty acids in milk. Since enzyme is made up of protein which easily affected by varies temperature. This

Enzymes are catalysts that speed up chemical reaction but are not themselves consumed or changed by the reaction. The cell’s biological catalysts are proteins. Proteins are made up of one or more polypeptide chains that are folded to make an active site‚ an area in which a material to be acted on by the enzyme‚ called the substrate‚ will fit. The temperature‚pH‚ the concentration of enzyme‚ and the concentration of substrate all affect the activity of the enzyme and the rate of the reaction. The

The effect of time on enzyme reaction. Abstract: In this lab investigation we will observe how the amount of hydrogen peroxide is affected by catalase over time. The enzyme was added to 10 mL’s of hydrogen peroxide and observed over time to determine the relation between time and enzyme activity. The hypothesis stated that as time increased substrate would decrease. Therefore I predicted that at 60 seconds‚ there would be the least amount of H2O2. The enzyme activity mirrored my predictions

was designed to investigate the effects of temperature on reactions between the enzyme catalase found in animal tissue with the substrate H2O2. The hypothesis stated that an increase in the temperature of the substrate would create a subsequent increase in the rate of reaction between the enzyme and the substrate. This hypothesis was tested by immersing 1cm cubes of animal tissue (sheep liver) which contained the enzyme catalase into the substrate (H2O2 ) mixed with detergent which foamed showing a

A peroxidase enzyme‚ which was extracted from a brassica compestris (turnip)‚ is tested under various conditions in temperature‚ pH level‚ and competitive inhibitor (hydroxylamine). ABSTRACT: In order to determine the properties of an enzyme‚ a peroxidase enzyme was extracted from a brassica compestris (turnip) and tested under various temperatures‚ pH levels‚ and by a competitive inhibitor (hydroxylamine). The enzyme activity was measured in various ways depending on the activity. Temperature

Patrick McCrystal Enzymes: Natural Catalysts Enzymes are catalytic proteins‚ meaning they speed up chemical reactions without beingused up or altered permanently in the process. Although various enzymes use different methods‚all accomplish catalysis by lowering the activation energy for the reaction‚ thus allowing it tooccur more easily. Enzymes have very specific shapes (conformations). Part of the conformationis the active site of the enzyme‚ where the actual catalysis occurs. The specific molecule
