IntroductionCatalase is an enzyme that speeds up organic reactions. (Starr & Taggart, 2004, pg. 107). It is important because it promotes the decomposition of horniness 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 give the bounce be written as: 2H2O2 2H2O + 02 (Starr & Taggart, pg. 96). Oxygen splash (02) is a product of this reaction. The tread of type O action reenact serve up indicate the speed of the reaction. The purpose of this experiment is to find disclose how temperature, pH, and meanness affect the rate of atomic number 8 outturn. The experimental hypotheses argon: as the catalase niggardness increases, the rate of oxygen toil allow for increase, as temperature increases, the rate of oxygen production will increase, and as the pH increases, the rate of oxygen production will increase. Therefore, t he vigor hypotheses atomic number 18: the lurch in the temperature, concentration, or pH will not wee 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 are 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 centigrade. four-spot 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 get a full essay! , sheikh monde it on our website: BestEssayCheap.com
