Catalase

Biology Coursework Title: Catalase: The effect of temperature on Beef colored and Potato catalase action. Research: All enzymes ar proteins, meaning that they be polymers of amino acids. Their tertiary structure gives them a globular devote due to the stick to posit in the molecule. Many types of bonds choke up the structure together and in the right shape. They strongest of these atomic number 18 the di-sulphide bridge over between two cysteine amino acids. Also play be hydrogen bonds, although singly week when many atomic number 18 present the bond is strong. In addition are hydrophobic non-polar R-groups which by pointing to the middle of the molecule act as a bond force. Catalase, like all enzymes, is a biological catalyst. Catalase is an enzyme that speeds up the air division of hydrogen bleach into water (H2O) and oxygen gas (O2). 2H2O2--------catalase--------------> 2H2O + O2 natural heat peroxide (H2O2) is a poisonous byproduct of metabolic pr ocess that bed damage cells if it is not removed. Catalase is an example of a in particular efficient enzyme.   Catalase has one of the broad(prenominal)est turnover numbers for all cognize enzymes (40,000,000 molecules/second).

 This high rate shows an importance for the enzymes capability for detoxifying hydrogen peroxide and preventing the organic law of carbon dioxide bubbles in the blood The main(prenominal) properties of enzymes are as follows: They in the main work real rapidly They are not destroyed by the response which they catalyse. They can work in either direction They are inactivated by high temperatures. They are sensitive to pH They are commonly spe cific to particular reactions It is affe! cted by the pursual factors: pH The precise three-dimensional molecular shape which is resilient to the mathematical operation of enzymes is partly the result of hydrogen bonding. These bonds whitethorn be embarrassed by the concentration of hydrogen ions (H+) present. pH is a pace of hydrogen ion concentration. It is measured on a scale of 1-14, with pH 7 being the neutral point....If you inadequacy to get a full essay, order it on our website: OrderEssay.net
