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

Aim: To find the effect of temperature on enzymes, using a washrag potato vine as a catalyst. The source of catalase is in the potato cells. 2H2O2 ? O2 + H2O Planning: Introduction: An Enzyme is each one of legion(predicate) specialised organic substances, be of polymers of aminic acids, that act as catalysts to regulate the speed of the much chemic chemical reactions involved in the metabolism of living organisms Enzymes argon assort into several ample categories, such(prenominal) as hydrolytic, oxidising, and cut down, depending on the fount of reaction they attend. Hydrolytic enzymes accelerate reactions in which a substance is lowly down into simpler compounds through reaction with water molecules. Oxidising enzymes, known as oxidises, accelerate oxidation reactions; reducing enzymes speed up fall reactions, in which oxygen is removed. umpteen former(a) enzymes catalyse other types of reactions. Individual enzymes be named by adding ASE to the name of the substrate with which they react. The enzyme that controls urea buncombe is called urease; those that control protein hydrolyses be known as proteinases. However, some enzymes, such as the proteinases trypsin and pepsin, retain the names apply before this lyric was adopted Enzymes argon large proteins that speed up chemical reactions.

In their circular structure, one or more polypeptide chains colour and fold, carry to exciteher a undersize number of amino class acids to form the active site, or the location on the enzyme where the substrate constipates and the reaction takes place. Enzyme and substrate erupt to bind if their shapes do non run across 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 sufficient of increasing the rate...
