Snow · Answer 1

Answer: H2O2 is the reactant (substrate)

Explanation: The substrate would be hydrogen peroxide (H2O2) which is a reactive oxygen species or ROS. Hydrogen peroxide is dangerous because it is capable to oxidize other substance and should be broken down to water (H2O) and oxygen (O2) to prevent damaging the cell.
