Lab Report on Effect of Enzymes Essay

ntroduction

The enzyme catalase is present in cells in order to rush the dislocation of H peroxide ( H2O2 ) . which is a toxic chemical to the human organic structure. When H peroxide is broken down. the terminal merchandises are Water ( H2O ) and Oxygen ( O2 ) . In this study. the reaction of catalase to hydrogen peroxide is being tested. Furthermore. the effects of temperature. concentration. and pH degree on this reaction are being considered. We hypothesize that he experiments will demo that Catalase speeds the dislocation of H peroxide to H2O and O. and the O will bring forth a larger bubbling consequence in the solutions where the optimal conditions for enzymatic activity are present. These optimal conditions should be in warm temperature. high concentration. and high pH degrees. First. the reaction of catalase to hydrogen peroxide is tested with no extra factors. Then. to analyze the consequence of temperature. three scopes of temperature are introduced in the 2nd experiment. Following. to analyze the consequence of concentration. three different degrees of catalase are studied in the 3rd experiment. And eventually. to analyze the consequence of pH. solutions with three degrees of H concentration are tested in the 4th experiment. once more with H peroxide and catalase.

Methods

Experiment 1: To prove the catalase-hydrogen peroxide reaction with no extra factors. we marked three trial tubings to the 1 centimeter and 5 centimeter Markss. Catalase was added to the 1 cm grade of trial tubing 1 and prove tubing 3. while trial tubing 2 was filled to the 1 centimeters grade with H2O. Hydrogen peroxide was added to the 5 centimeter grade in trial tubing 1 and prove tubing 2. while a sucrose solution was used to make full prove tubing 3. All trial tubings were assorted and we waited 20 seconds for bubbling. Test tube 1 represented the experiment. while trial tubing 2 was the negative control for H peroxide. and trial tubing 3 was the negative control for the catalase. Experiment 2: To prove the consequence of temperature on enzyme activity. the solution created in trial tubing 1 of the old experiment was recreated in three separate trial tubing. Test tube 1 was placed in an ice bath. Test 2 was placed in warm H2O. Test tube 3 was placed in boiling H2O. Experiment 3: To prove the consequence of concentration. three separate trial tubings were set of to hold three different concentrations of the reactant ( catalase ) . while the substrate was consistent across all three trial tubings.

Test tubing 1 was filled in the same manner as trial tubing 1 in the first experiment. Test tube 2 was so filled to 2 centimeter with catalase and so to 7 centimeter with H peroxide. Test tube 3 was filled to 3 centimeter with catalase. and so to 8 centimeter with H peroxide. Experiment 4: Finally. to prove the consequence of pH Level on enzyme activity. three trial tubings were once more created. The concentration of catalase and H peroxide are once more the same as in trial tubing one in the first experiment. However. 2 centimeter of H2O adjusted to different pH degrees were added. In trial tubing 1. 2 centimeter of H2O with pH of 3 is added to the 1 centimeter of catalase and 4 centimeter of H peroxide. In trial tubing 2. 2 centimeter of H2O adjusted to the pH adjusted to 7 was added to 1 centimeter of catalase and 4 centimeter of H peroxide. In trial tubing 3. 2 centimeter of H2O adjusted to the pH adjusted to 11 was added to 1 centimeter of catalase and 4 centimeter of H peroxide.
