Action Of Enzyme Catalase On Hydrogen Peroxide
Pages 5 (1255 words)
Catalase is an enzyme present in the cells of plants, animals and aerobic (oxygen requiring) bacteria. It promotes the conversion of hydrogen peroxide, a powerful and potentially harmful oxidizing agent, to water and molecular oxygen.
The student feels that the more the concentration of the liver the more the enzyme that would result since more amount of oxygen would react with the hydrogen peroxide molecules. For accomplishing this, the student has taken five test tubes with the first test tube having twice the suspension as that of the fifth tube expecting that there would be twice the amount of oxygen given off. This seems that the student wants to prove that the amount of oxygen that would be evolved would be directly proportional to the amount of the liver suspension take. Since it cannot be decided in a single experiment the student repeats it three times to observe whether the desired changes have taken place in each experiment or not. The independent variable to be considered here would be the amount of liver suspension and distilled water and the dependent variable would be the amount of oxygen evolved. This experiment deals with quantitative analysis. ...
