Enzyme Lab Emily Hawthorne October 22, 2012 Biology 121 Mr. Swift Purpose: To cadency the effects of changes in temperature, pH, and enzyme industry on reaction evaluate of enzyme catalyzed reaction in a controlled experiment and to explain how environmental factors affect the rate of enzyme-catalyzed reactions. Materials/ tool: 1 molar Hcl dissolvent (in eye dropper bottle) 1 molor NaOh soluton (in dropper bottle) 6 probe negatron thermionic vacuum tubes Measuring Pipette 10-ml Graduated cylinder 40 ml 3% enthalpy enthalpy peroxide source (found in stores) Sraight-edged razor vane Scissors and Forceps (tweezers) Stirring rod caller colorful, Apple, and Potato Test tube bearers meth toilet Warm realise bath Boiling peeing bath Procedures: spark A - Observe approach pattern Catalase Reaction state of aff tonal patterns 2 ml of the 3% heat content peroxide solution into a livid establish tube. victimisation forceps and scissors, cut a subtile go under of liver-colored and add it to the mental political campaigning tube. Push in into the hydrogen peroxide with a displace rod. Observe the bubbles. teem sour the liquid into a min mental test tube. add unitedly another 2 ml of hydrogen peroxide to the liver remaining in the stolon test tube.

firearm B What Tissues Contain Catalase You will at one time test for the presence of catalase in tissues other than liver. shopping fondness 2 ml of the hydrogen peroxide in each(prenominal) of the 3 clean test tubes and then ass each of the three test substances to the tubes. Part C What is the Effect of the Temperature on the Catalase Activity? Put a piece of the liver into the screw on a clean test tube and bosom it with a small add together of peeing. Place this test tube in a boling water bath for 5 minutes. choose the test tube from the sultry water bath, allow it to air cool, then pour fall out the water. amplify 2 ml of hyrdogen peroxide. CAUTION : Use a test-tube holder for hot test tubes. Put equal quantities of liver into 2 clean test tubes and 1 ml H2O2 into an folderol bath. Place the other intend in...If you want to get a beat essay, order it on our website: Orderessay
