Homework Answers
Hydrogen peroxide is harmful to cells , hence it is immediately converted to less reactive water and oxygen by the enzyme Catalase.
catalase also protects the cell from oxidative damage by
reactive oxygen species.

4. Now consider the catalase catalyzed decomposition of hydrogen peroxide to water. The much needed catalyst. 2H202 + catalase → 2H2O + O2 + catalase a. [3] Assume the following mechanism: H2O2 + catalase = {H202-catalase} HIS 54 Inhibitor ASN 127 H2O2 + {H202-catalase} → catalase + 2H20 + O2 Oxygen When the pre-equilibrium approximation is used, the rate-law is: 41 dt Kegk2[H202]?[E]. The steady-state approximation gives a more general rate law. Derive the rate law using the SS approximation....

The enzyme catalase catalyzes the decomposition of hydrogen
peroxide. The following data are obtained regarding the rate of
reaction as a function of substrate concentration using
concentration of catalase equals to 3.5 x 10^–9 M : Analyzing the
data using the Lineweaver-Burk plot:
