Enzyme properties
Increase reaction rate, are not changed by the reaction, do not change the nature of the reaction, lowers the activation energy
Catalase
Enzyme converts hydrogen peroxide to water and oxygen gas to prevent damaging effects on cells from free radicals
Catalase equation
2H202 → 2H20 + O2
Adding nails to hydrogen peroxide
Reduces iron (III) ions to iron (II) ions
Peroxidase
Breaks down H2O2 and organic substrate into water and oxidized substrate like oxidized guaiacol
