Question

What are the roles of hydrogen peroxide, oxygen, hydrogen, and catalase in the following chemical reaction?

catalase 2H2O2 -O2 + 2H2O
A. Catalase is an enzyme, O2 and H2O are substrates, and H2O2 is a reactant.
B.Catalase is a substrate, O2 and H2O are substrates, and H2O2 is an enzyme.
C.Catalase is a substrate, O2 and H2O are products, and H2O2 is an enzyme.

D.Catalase is an enzyme, O2 and H2O are products, and H2O2 is a substrate.

Answer 1

The roles of hydrogen peroxide, oxygen, hydrogen, and catalase in the following chemical reaction the roles of hydrogen peroxide, oxygen, hydrogen, and catalase in the following chemical reaction.

Answer 2

D. Catalase is an enzyme, O₂ and H₂O are products, and H₂O₂ is a substrate.

Step-by-step explanation:

As per the given reaction the compound (H₂O₂) on the left side of the equation is the reactant or substrate and the two compounds (O₂ and H₂O₂ )on the right side is the product. Catalase is neither a reactant nor product, it is a catalyst. The role of a catalyst is to accelerate the rate of a reaction by lowering the activation energy of the reaction without itself undergoing any change.
