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 wizard of many specialised organic substances, composed of polymers of aminic acids, that take on as catalysts to regulate the speed of the many chemic reactions voluminous in the metabolism of living organisms Enzymes are assort into some(prenominal) broad categories, such(prenominal) as hydrolytic, oxidising, and reducing, depending on the lawsuit of reaction they control. Hydrolytic enzymes quicken reactions in which a substance is miserable down into simpler compounds with reaction with water molecules. Oxidising enzymes, known as oxidises, accelerate oxidation reactions; reducing enzymes speed up diminution reactions, in which oxygen is removed. Many former(a) enzymes catalyse other types of reactions. Individual enzymes are named by add ing 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, persist in the names used before this lyric was adopted Enzymes are large proteins that speed up chemical reactions.

In their global structure, one or more polypeptide chains colour and fold, pitch together a small number of amino free radical acids to form the active site, or the location on the enzyme where the substratum binds and the reaction takes place. Enzyme and substrate fail to bind if their shapes do non equip exactly. 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...
