What is catalase enzyme (enzyme activated by iron)?

Dear student

Please refer the solution below for the said query


Catalase is the enzyme that catalyses the breakdown of hydrogen peroxide to water and oxygen. The Fe2+ is a cofactor in enzyme catalase that helps it to bind with the substrate (hydrogen peroxide). It is almost present in all living organisms which are exposed to oxygen as it protects the cells from oxidative damage by oxygen. 



Hope this information clears your doubt about the topic.
