To 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 plants (potato, purple cabbage) in oxygen and waterMotivation: The reason why I chose this topic was because I wanted to know what enzymes are used for, to what extent they are used in our body and what is the extent of their applications in the food industry. Enzymes have been used in research, primarily because of their ability to facilitate reactions without being modified themselves as well as their ability to speed up these reactions, which would otherwise take much longer. And it is these two characteristics that compel me to deepen my research into the applications of enzymes. Their applications in food processing are what interests me the most. Food enzymes are proteins that are used as catalysts in various biochemical processes to improve the quality of different food products like milk and baked goods like bread. Enzymes have also been used in wine production, food packaging and dairy processing. This is why I chose to study the quantity of catalase present in animal products (liver, milk, honey) and plants (potatoes, purple cabbage) by measuring the quantity 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 to useful elements in the body like water and molecular oxygen .Conceptual diagramLiterature reviewBefore we can even begin to understand catalase we must first understand what an enzyme is. The enzymes are organic... middle of paper ...... l of distilled water, mix for 2 minutes on high speed until the mixture is smooth and free of lumps (measure the weight of the cabbage using balance aid).12. Label five test tubes; A, B, C, D and E with 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 test tube C using a measuring cylinder.16. Place 5 ml of mixed purple cabbage into test tube D using a measuring cylinder.17. Place 5g of potato in the E18 test tube. Be sure to clean the syringe and measuring tube after each use to avoid cross-contamination.19. Place the five test tubes on the test tube rack.20. In each test tube, place 5 ml of pure hydrogen peroxide into each test tube using the syringe.21. Observe the result.22. Record the results by measuring the amount of foam produced and tabulate them.
