The enzyme catalase catalyzes the decomposition of hydrogen peroxide:
2 H2O2 ------------> 2 H2O + O2
The turnover number (kcat) for catalase is 40,000,000 sec-1. The Km of catalase for its substrate is 0.11 M.
a) In an experiment using 3 nanomole/mL of catalase, what is Vmax?
b) What is V0 when [H2O2] is 0.75 M?
c) What is the catalytic efficiency of catalase?
d) Does catalase approach “catalytic perfection”?
