In experiment one (i.e. the effect of varying substrate concentration on the rate of enzyme-catalase reaction) we tested the hypothesis HA as substrate concentration increases‚ so will reaction rate until all active sites are bound. In experiment two (i.e. The effect of temperature on the rate of enzyme-catalase reaction) we tested the hypothesis HA as temperature increases‚ so will

CATALASE Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It catalyzes the decomposition of hydrogen peroxide to water and oxygen. It is a very important enzyme in reproductive reactions. Likewise‚ catalase has one of the highest turnover numbers of all enzymes; one catalase molecule can convert millions of molecules of hydrogen peroxide to water and oxygen each second. Catalase is a tetramer of four polypeptide chains‚ each over 500 amino acids long. It contains

Effect of an Orange on Catalase Activity in Comparison with a Potato Introduction Catalysts are substances that increase chemical reactions while using less energy. They also remain unchanged after use‚ which enables it to be used repeatedly. Cells have special catalysts called enzymes‚ which are specialized proteins that help accelerate chemical cell reactions. (Evert‚ RF & Eichhorn‚ SE 2013). Enzymes also control plant metabolic processes such as respiration (Evert RF‚ Eichhorn SE & Perry JB

INVESTIGATION INTO THE EFFECT OF TEMPERATURE ON CATALASE ACTIVITY AIM The aim of this experiment is to find out the effect of temperature on catalase or hydrogen peroxide. This will enable us to tell at what temperature hydrogen peroxide is most efficient. This (degradation) reaction will help us determine some of the catalase’s different attributes. HYPOTHESIS In this experiment it would be safe to hypothesise that no activity would take place at 1 to 20 degrees. It would be probable that a

experiment shows the effects of changing the pH level has on Catalase. As predicted‚ the farther away the pH levels got from the optimum pH (7.2)‚ the lower the reaction rate. At a pH of 7.2‚ the foam of the reaction measures 6cm. At a ph of 3 it measures 2.5 cm‚ at a pH of 5 it measures 2.75 cm‚ at ph 9 it measures 2.3 and at 11cm it measures 2cm. pH measures the hydrogen ion concentration of a substrate. By changing the pH of the catalase‚ the enzyme was denatured. Denaturing is the result of altering

Lab Report The effect of temperature on the reaction between Catalase and H2O2 Sarah AlShemesi In this experiment we’ll be exploring the effects of temperature on the reaction between Catalase and H2O2.We’ll be using five different temperatures to test this. The five different temperatures will be 10‚ 30‚ 50‚ 70 and 90 oC. We will use the liver as a source of Catalase. A 1 gram piece of liver will be inserted into a test tube with 2 cm3 of water‚ then 2 cm3 of H2O2 will be added. The Catalase

Abstract The aim of this study was to test the rate of reactivity of the enzyme catalase on hydrogen peroxide while subject to different concentrations of an inhibitor. The hypothesis was that hydrogen peroxide will be broken down by catalase into hydrogen and oxygen‚ where a higher concentration of inhibitor will yield less oxygen‚ resultant of a lower rate of reaction. Crushed potato samples of equal weight were placed in hydrogen peroxide solutions of various temperatures. The results showed
