1. Using MnO2 and Enzymes without any heat treatment:
MnO2 and cellular enzymes (catalase/peroxidase) causes breakdown of H2O2 and evolution of oxygen.
2. Using MnO2 and Enzymes after heat treatment:
Oxygen evolves in the H2O2 solution containing boiled and cooled MnO2 . But oxygen does not evolve in the tube containing the enzyme.
3. This confirms that heat affects the enzyme and inactivates it whereas heat does not have any effect on inorganic catalyst.
