Study the amount of oxygen foam (cm) produced by the enzyme catalase when it breaks down hydrogen peroxide in animal cells (liver, milk, honey) and plant cells (potatoes, purple cabbage ) in oxygen and water Reason: The reason why I chose this topic is because I wanted to find out what enzymes are used for, to what extent they are used in our body and how wide their applications are in the food industries. Enzymes have been used in research , mainly due to their ability to facilitate reactions without being modified and their ability to accelerate these reactions, which would otherwise require a much longer period of time to complete. And it is precisely these two characteristics that push me to conduct further research on the applications of enzymes. What interests me most is their application in food processing. Food enzymes are proteins used as catalysts in a variety of biochemical processes aimed at improving the quality of different food products such as milk and baked goods such as bread. Enzymes have also been used in wine production, food packaging, and dairy processing. For this reason I chose to investigate the amount of catalase present in animal products (liver, milk, honey) and vegetable products (potatoes, purple cabbage) by measuring the amount of oxygen foam produced (cm) when these products are exposed to hydrogen peroxide. . Catalase is found in every cell of every organism on earth, in humans it is used to break down hydrogen peroxide, which is toxic to humans, into elements useful to the body such as water and molecular oxygen. Conceptual Diagram Literature Review Before we even begin to understand catalase we must first understand what an enzyme is. The enzymes are organic... half of paper... l of distilled water, blend for 2 minutes at high speed until the mixture is smooth and without lumps (measure the weight of the cabbage using the scale).12 . Label five test tubes; A, B, C, D and E with the permanent marker.13. Place 5 ml of honey into test tube A using a syringe.14. Place 5 ml of milk into test tube B using a syringe.15. Place 5 ml of mixed liver into tube C using a graduated cylinder.16. Place 5 ml of blended purple cabbage into test tube D using a graduated cylinder.17. Place 5 g of potatoes in the E18 test tube. Be sure to clean the syringe and graduated cylinder after each use to prevent cross-contamination.19. Place all five tubes on the tube holder.20. Into each test tube, pour 5 ml of pure hydrogen peroxide using the syringe.21. Observe the result.22. Record the results by measuring the amount of foam produced and tabulate them.
