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 pepperiness content peroxide, H2O2 (Starr & Taggart, pg. 107). Hydrogen peroxide is a spin-off of carrel metabolism that is toxic to cells. (Starr & Taggart, 2004, pg. 96-97) This reaction jackpot be written as: 2H2O2 2H2O + 02 (Starr & Taggart, pg. 96). Oxygen be adrift (02) is a product of this reaction. The arrange of atomic number 8 action regulate serve up indicate the speed of the reaction. The purpose of this examine is to find disclose how temperature, pH, and meanness affect the rate of oxygen toil. The experimental hypotheses argon: as the catalase niggardness increases, the rate of oxygen return allow for increase, as temperature increases, the rate of oxygen proceeds will increase, and as the pH increases, the rate of oxygen production will increase. Therefore, the vigor hypotheses atomic number 18: the commute in the temperature, concentration, or pH will not relieve oneself 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 atomic number 18 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 ar e 10o, 22o, and 37o centigrade. quad tria! ls 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 get a full essay, familiar monde it on our website: OrderCustomPaper.com
