Question

Peroxidase is an enzyme that breaks down hydrogen peroxide in cells. It accomplishes this because of its structure. What part of the enzyme is involved in catalytic activity

Answer 1

Answer:

The answer is a heme cofactor.

Explanation:

Peroxidase is an enzyme that catalyzes oxidation/reduction reaction by using hydrogen peroxide as a substrate.  

Donor+H2O2 ↔ Oxidized donor + H2O

Peroxidase active site can contain a heme cofactor that has an iron ion and a porphyrin molecule that acts as an electron donor to the hydrogen peroxide which is then reduced to water.
