Question

(A) The catalytic decomposition of hydrogen peroxide by the enzyme catalase is showing below: 2 H;O2=2 H¿0 + O, In an experiment 5 µmole/L of the enzyme catalase was used to decompose 0.50 M H2O2. The Km of catalase for H2O2 is 0.15 M and the Vmax of the reaction is determined as 100 mol/L- s. Using Michaelis-Menten equation, calculate the rate of the reaction, the turnover number, and the catalytic efficiency for catalase.
