Temperature of Hydrogen Peroxide on Speed of Decomposition Reaction of Chicken Liver
Problem: What effect does the temperature of hydrogen peroxide, in degrees Celsius have on the speed of the decomposing the chicken live and produce oxygen and hydrogen, measured in terms of the height of the bubbles produced in centimetres(cm)?
Background Information: Hydrogen peroxide is a by product of many reactions in our body. When enzymes break down amino acids and fatty acids they make large amounts of hydrogen peroxide. High amount of hydrogen peroxide can cause chemical burns and tissue damage. Catalase is a common enzyme found in most living organisms. Catalase is frequently used by cells to rapidly catalyze the decomposition of hydrogen peroxide into less reactive gaseous oxygen and water molecules. Biological catalyst is usually found in high concentrations in the liver. It catalyzes the decomposition of hydrogen peroxide into oxygen and water. The optimum temperature for it is 37oC and once the temperature is above 40oC, the catalase begins to denature and eventually coagulates. Also, for every 10°C increase in temperature, there is a double in the rate of reactions of enzymes within a certain range.
