Dustin Lee 11/13/2006 Biology Block C Introduction: In class, we learned that all living organisms produce hydrogen peroxide as a byproduct of chemical reactions. Peroxide is toxic to living cells and must be broken down. Peroxide can be broken down by an enzyme called catalase. In the lab we did in class, we tried to answer some basic questions. Question: Is catalase found in both plant and animal cells? Hypothesis: Both the plant and animal cells will test positive for catalase, but the fungus won’t. Materials: Hydrogen peroxide, liver puree, grinded plant cells, and yeast (mixed in water) Procedure: 1. Fill test tube with 3 mL of H 2 O 2 2. Using eyedropper put 3 drops of the liver puree in the test tube 3. Repeat step 1 4. Grind up plant 5. Put plant cells in the test tube 6. Repeat step 1 7. Mix yeast with water 8. Put 3 drops of yeast in the test tube Analysis Questions 1. No, my results did not agree with what I hypothesized. The liver puree held the best results in terms of the amount of reactions.
