Catalase

Biology Coursework Title: Catalase: The effect of temperature on Beef liver-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 perk up due to the stick to posit in the molecule. Many types of bonds deflect the structure together and in the right shape. They strongest of these ar the di-sulphide straddle between two cysteine amino acids. Also invest are hydrogen bonds, although singly week when many are 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 bind force. Catalase, like all enzymes, is a biological catalyst. Catalase is an enzyme that speeds up the partition off of hydrogen peroxide into water (H2O) and oxygen gas (O2). 2H2O2--------catalase--------------> 2H2O + O2 fall heat peroxide (H2O2) is a poisonous byproduct of metabolism that bed damage cells if it is not removed. Catalase is an example of a specially 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 briny properties of enzymes are as follows: They in the main work precise rapidly They are not destroyed by the reply which they catalyse. They can work in either direction They are inactivated by high temperatures. They are sensitive to pH They are common ly specific to particular reactions It i! s affected by the adjacent factors: pH The precise three-dimensional molecular shape which is decisive to the mathematical operation of enzymes is partly the result of hydrogen bonding. These bonds may 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 compulsion to get a full essay, order it on our website: BestEssayCheap.com
