|
|
H2O + O2
|
|
|
H2O2 + O2
|
|
|
CO2 + O2

Explanation:
Detailed explanation-1: -The conversion of hydrogen peroxide to water and oxygen by catalase is a well understood two-step process whereby catalase heme Fe+3 reduces one molecule of hydrogen peroxide to water, generating a covalent Fe+4O oxyferryl species and a porphyrin cation radical.
Detailed explanation-2: -Catalases (EC 1.11. 1.6) are antioxidant enzymes that catalyze the conversion of hydrogen peroxide to water and molecular oxygen.
Detailed explanation-3: -Catalase breaks down two hydrogen peroxide molecules into one molecule of oxygen [9] and two molecules of water in a two-step reaction [10].
Detailed explanation-4: -Hydrogen peroxide dissociates to give water and oxygen gas. 2 H 2 O 2 ( l )
