An Investigation Into The Rate of Reaction of The Catalase Enzyme :: Papers

An Investigation Into The Rate of Reaction of The Catalase Enzyme Introduction: In this experiment I will attempt to investigate the factors that effect the rate of reaction of the catalyse enzyme. Catalyse is an enzyme found in food such as potato and liver. It is used for removing hydrogen peroxide because of the shape of the hydrogen peroxide molecule; this type of reaction is when a molecule Is broken down into smaller pieces called catabolic reaction. Enzymes are proteins e.g. catalyse. They are made in cells. A catalyst is something that speeds up a reaction. One molecule can usually be used many times. All enzymes work at different pHs because they have different jobs to do but you cant use a ph which isn't suitable for that particular enzyme which you are using, other wise the enzyme will de nature. Enzymes also react with tempreture but like the ph the temperature cant be unsuitable to the enzyme other wise it will de nature or slow down the enzymes which would make it very difficult to obtain accurate and reliable results. A carbohydrase enzyme is different to a catalyse enzyme and other enzymes because enzymes have different patterns (shape). Enzymes are like keys to different substrates like e.g. fat, sugar and the substrates are like keyholes.
