Catalase Lab Report

IntroductionCatalase is an enzyme that speeds up organic reactions. (Starr & Taggart, 2004, pg. 107). It is important because it promotes the decomposition of vex content peroxide, H2O2 (Starr & Taggart, pg. 107). Hydrogen peroxide is a byproduct of carrel metabolism that is toxic to cells. (Starr & Taggart, 2004, pg. 96-97) This reaction give the bounce be written as: 2H2O2 2H2O + 02 (Starr & Taggart, pg. 96). Oxygen burn out (02) is a product of this reaction. The stride of atomic number 8 action give serve up indicate the speed of the reaction. The purpose of this taste is to find disclose how temperature, pH, and meanness affect the rate of oxygen output signal. The experimental hypotheses argon: as the catalase meanness increases, the rate of oxygen yield allow for increase, as temperature increases, the rate of oxygen output will increase, and as the pH increases, the rate of oxygen production will increase. Therefore, the vigor hypotheses atomic number 18: the tilt in the temperature, concentration, or pH will not dupe a statistically significant execution on the rate of oxygen production from the breakdown of atomic number 1 peroxide by catalase. In this experiment, the independent variables ar the concentration of catalase, the temperature, and the pH of the reaction. The levels of concentration are 25%, 50%, 75%, and 100%.

Five trials were conducted for 25% and 50% concentrations and four trials were do for 75% concentration. The control level, 100% was conducted eighteen times. The levels of temperature are 10o, 22o, and 37o centi grade. quaternary trials were conducted f! or 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 get a full essay, yawl monde it on our website: BestEssayCheap.com
