Introduction:
The purpose of this experiment is to identify the effects of temperature of cells on catalase reaction. Catalase is an enzyme that is found in cells of many living tissues. When experimenting with cells on a relevant topic the rate of enzyme activity (catalase reaction) was strong in the average temperature than in the boiled temperature. When researching this topic I was astonished by how much I learned about the enzyme. Catalase is a very common enzyme found in most organisms that are exposed to oxygen. One molecule of catalase can convert 40 million molecules of hydrogen peroxide to water and oxygen. Hydrogen peroxide is a harmful product of normal processes to prevent damage to cells and tissue so it must be converted into less hazardous substances. Hydrogen peroxide is said to denature cells meaning to kill cells.

Temperature can affect the rate of enzyme reaction, according to the laws of thermodynamics. As the temperature increases the rate the...
