Overview of Enzyme Activity Lab
In this lab we had to create catalyze reactions using hydrogen peroxide. We used beef liver, chicken liver, potato, and apple to show the effects of change with temperature, pH levels, and environment factors on enzyme catalyzed reactions. We learned that substances with a different amount of catalase have different reaction rates. We also learned that temperature and pH levels can denature the original enzyme.
Background Information on Enzymes
Enzymes are protein catalysts that increase the rate of chemical reactions. It is known as a "substrate specific". The substrate is the molecule or compound an enzyme will react with, which means one enzyme will only react with one specific molecule.
The catalase reaction in enzymes are important to living things because it helps maintain homeostasis. Cells produce hydrogen peroxide (H2O2). If H2O2 wasn't broken down, then it would poison and kill the cell. In order to maintain homeostasis, most cell of the human body must generally be kept between the pH of 6.5 and 7.5.
