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.

I really don't understand the answer. I think it's A but I'm not sure

anonymous · Answer

Catalase is an enzyme that catalyzes the decomposition of hydrogen peroxide to water and oxygen.
Can you figure it out with just this sentence?

anonymous · Answer

I still don't understand

anonymous · Answer

A  substrate is a molecule that an enzyme acts on.

anonymous · Answer

So what is the enzyme acting on?

anonymous · Answer

A product of a chemical reaction is the molecules it creates.
