Question

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

Catalase: 2H2O2 --> 02 + 2H2O

A. Catalase is an enzyme, O2 and H2O are substances, and H2O2 is a reactant.
B. Catalase is a substrate, O2 and H2O are products, 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 answer is D

Step-by-step explanation:

because it is

Answer 2

we are given with the equation 2H2O2 --> 02 + 2H2O . In an equation, the right-hand side contains the products while the left-hand side consists of the reactants or substrate. In this case, the enzyme used to enhance the rate of the process is catalase. The answer hence is D. Catalase is an enzyme, O2 and H2O are products, and H2O2 is a substrate.
