The reaction rates of the enzyme in 6%, 4%, 2%, 1% and 0.5% concentration of Hydrogen Peroxide were 1.56 mL/s, 1.54 mL/s, 1.01 mL/s, 0.56 mL/s and 0.23 mL/s respectively. When the liver was added in distilled water and detergent it did not react. It was observed in the lab that the optimum concentration for enzyme activity is when the substrate concentration is 6%. After the optimum substrate concentration is reached, the reaction rate levels off because as the substrate concentration increases the active sites get occupied with the substrate and there are not enough active sites to break down all of the Hydrogen Peroxide molecules. At this point virtually all the active sites are occupied so the active sites are saturated with Hydrogen Peroxide. Increasing the Hydrogen

1. Explain the test you could perform to show that oxygen gas evolved from the reactions.

* One cube of liver was then placed inside the graduated cylinder.
