To determine if changes in room temperature will have an effect on the activity of an enzyme Materials: -6 test tubes -Hot water bath -Liver -Test tube rack - Thermometer -Hydrogen Peroxide -10ml graduated cylinder - 3 250ml beakers -Distilled water -Tweezers -Ice bath Hypothesis: As temperature decreases, enzyme activity decreases until it is too cold for the enzyme to function. As temperature increases, enzyme activity increases until it is too hot for the enzyme to function and enzyme denatures. Conclusion: In this lab 4 pieces of the same liver were mixed with hydrogen peroxide at different temperatures. In test tube 1, at room temperature, hydrogen peroxide was added to the liver which resulted in a quick reaction and the heat was released. In test tube 2, at zero degrees Celsius, the reaction was not as active but gas was still produced. In test tube 3 at 100 degrees Celsius,…show more content…
The reaction rate would increase as the surface area of the liver increases because only things in contact can react. The more surface area, the more room there is for the hydrogen peroxide to react. Hydrogen peroxide is broken down into water and one oxygen, since 2H202→ 2H2O + O2 from the decomposition reaction Catalase helps convert hydrogen peroxide into hydrogen and oxygen. It is essential for all living organisms because catalase protects the cell balances and the production of hydrogen peroxide. Without it, hydrogen peroxide can be toxic and turned into dangerous hydroxyl radicals that can mutate DNA. 5) Amylase is a very important enzyme to human cells because they break down macromolecules such and starch into sugars(disaccharides & trisaccharides) so they can be further digested and absorbed by humans. Without amylase in the salivary glands and pancreas, the carbohydrates we eat would not be properly digested and we would not get the nutrients from the
