Catalase is the protein that catalyzes the decomposition of Hydrogen Peroxide to diatomic Hydrogen and Oxygen. Boiling the liver releases the Catalayse from the tissue, freeing it up to react when it comes in contact with hydrogen peroxide. When you mix crushed liver with hydrogen peroxide, why does it react more quickly than when you mix hydrogen peroxide with regular liver? Lesson organisation. Repeat steps 5 & 6 with the boiled and frozen potato sections. It only takes seconds! Hydrogen peroxide was used in this lab, it was decomposed at the molecular level by the enzyme catalase showing the chemistry portion of the biochemistry. Free radicals can cause damage to different parts of the body. Hydrogen peroxide is harmful and must be removed as soon as it is produced in the cell. This reaction is important to cells because hydrogen peroxide (H 2 O 2) is produced as a byproduct of many normal cellular reactions. For temperature it will be the temperature that is forty degrees Celsius because the enzymes in the liver will not exist after the temperature goes over forty degrees Celsius. Catalyse is a base, and Hydrogen Peroxide is an acid. Hydrogen peroxide is used to detect the presence of enzymes in liver, potato and celery, which catalyse the decomposition of hydrogen peroxide, by detecting the presence of the oxygen gas formed. Hydrogen peroxide (H 2 O 2) is a by-product of respiration and is made in all living cells. A larger amount of catalase lowers the activation energy, therefore speeds up the rate of reaction. The intense explosion it produces at high temperatures propels the rocket forward. If the cells did not break down the hydrogen peroxide, they would be poisoned and die. Result: When boiling the liver in water, heat downgrade the catalase in the liver making it incapable of processing the hydrogen peroxide therefore the boiled liver and hydrogen peroxide do not react. This should take no more than 20 - 30 minutes. Also, after superheating and supercooling the liver, we found that the reaction with the Hydrogen Peroxide was diminished. One of the reasons breaking down hydrogen peroxide is important is because if left alone, hydrogen peroxide in the blood can produce free radicals. and wash the test tubes out with detergent.
