The Effect of Temperature on the Rate of an Enzyme Catalysed Reaction

Aim: To find the effect of temperature on enzymes, using a white potato vine as a catalyst. The source of catalase is in the potato cells. 2H2O2 ? O2 + H2O Planning: Introduction: An Enzyme is each virtuoso of many specialised organic substances, composed of polymers of aminic acids, that profess as catalysts to regulate the speed of the many chemic reactions complicated in the metabolism of living organisms Enzymes be assort into some(prenominal) broad categories, such(prenominal) as hydrolytic, oxidising, and reducing, depending on the lawsuit of reaction they control. Hydrolytic enzymes advance reactions in which a substance is miserable down into simpler compounds through reaction with water molecules. Oxidising enzymes, known as oxidises, accelerate oxidization reactions; reducing enzymes speed up diminution reactions, in which type O is removed. Many former(a) enzymes catalyse other types of reactions. Individual enzymes be named b y adding ASE to the name of the substratum with which they react. The enzyme that controls urea buncombe is called urease; those that control protein hydrolyses are known as proteinases. However, some enzymes, such as the proteinases trypsin and pepsin, agree the names used before this lyric was adopted Enzymes are large proteins that speed up chemical reactions.

In their planetary structure, one or more polypeptide chains colour and fold, deliverance together a small number of amino assembly acids to form the active site, or the location on the enzyme where the substrate binds and the reaction takes place. Enzyme and substrate fai l to bind if their shapes do non mates exa! ctly. This ensures that the enzyme does not participate in the wrong reaction. The enzyme itself is unswayed by the reaction. When the products have been released, the enzyme is ready to bind with a unfermented substrate Properties of Enzymes enzymes are typical catalysts: they are capable of increasing the rate...
