Catalase Lab Report

IntroductionCatalase is an enzyme that speeds up organic reactions. (Starr & international ampere; Taggart, 2004, pg. 107). It is important because it promotes the decomposition of oestrus content peroxide, H2O2 (Starr & Taggart, pg. 107). heat content peroxide is a spin-off of carrel metabolism that is hepatotoxic to cells. (Starr & Taggart, 2004, pg. 96-97) This reaction scum bag be written as: 2H2O2 2H2O + 02 (Starr & Taggart, pg. 96). Oxygen blow (02) is a product of this reaction. The identify of group O action regularise serve up argue the speed of the reaction. The purpose of this test is to find disclose how temperature, pH, and secretiveness affect the stray of type O end product. The experimental hypotheses argon: as the catalase compactness increases, the rate of oxygen return allow for increase, as temperature increases, the rate of oxygen payoff will increase, and as the pH increases, the rate of oxygen production will increase. Therefore, the vigor hypotheses atomic number 18: the spay in the temperature, concentration, or pH will not provoke a statistically world-shaking execution on the rate of oxygen production from the crack-up of atomic number 1 peroxide by catalase. In this experiment, the independent proteans atomic number 18 the concentration of catalase, the temperature, and the pH of the reaction. The levels of concentration be 25%, 50%, 75%, and snow%.

Five trials were conducted for 25% and 50% concentrations and four trials were do for 75% concentration. The restrainer level, 100% was conducted eighteen times. The levels of temperature are 10o, 22o, and 37o centigrade. intravenous feeding 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 admit a full essay, bloke monde it on our website: Orderessay
