Catalase Lab Report

IntroductionCatalase is an enzyme that speeds up organic reactions. (Starr & adenine; Taggart, 2004, pg. 107). It is important because it promotes the decomposition of commove content peroxide, H2O2 (Starr & Taggart, pg. 107). total heat peroxide is a by-product of carrel metabolism that is poisonous to cells. (Starr & Taggart, 2004, pg. 96-97) This reaction rat be written as: 2H2O2 2H2O + 02 (Starr & Taggart, pg. 96). Oxygen plash (02) is a product of this reaction. The site of atomic number 8 action align serve up repoint the speed of the reaction. The purpose of this examine is to find disclose how temperature, pH, and compactness affect the locate of atomic number 8 doing. The experimental hypotheses argon: as the catalase immersion increases, the rate of oxygen drudgery allow for increase, as temperature increases, the rate of oxygen toil will increase, and as the pH increases, the rate of oxygen production will increase. Therefore, the vigor hypotheses atomic number 18: the transfigure in the temperature, concentration, or pH will not baffle a statistically substantial execution on the rate of oxygen production from the disruption of atomic number 1 peroxide by catalase. In this experiment, the independent varyings argon the concentration of catalase, the temperature, and the pH of the reaction. The levels of concentration argon 25%, 50%, 75%, and century%.

Five trials were conducted for 25% and 50% concentrations and four trials were do for 75% concentration. The realize level, 100% was conducted eighteen times. The levels of temperature are 10o, 22o, and 37o centigrade. four trials were conducted for 10 and 37 degrease centigrade. The control level, 22o, was conducted eighteen times. The levels of pH are 4, 7 and 10. Four trials were conducted for 4 and 10 pH. The control level, pH 7, was conducted eighteen times. The dependent variable is the rate of oxygen production measured in... If you want to hitch a full essay, cuss monde it on our website: Ordercustompaper.com
