Question

Identify the enzyme X in the following reaction.

\[\ce{H2O2(aq) ->[x] H2O(l) + \frac{1}{2} O2(g)}\]

Options

• Catalase

• Ferroxidase

• Amylase

• Carbonic anhydrase

Answer 1

Catalase

Explanation:

Catalase enzyme used in this reaction.

\[\ce{H2O2(aq) ->[Catalase] H2O(l) + \frac{1}{2} O2(g)}\]

It is a widespread enzyme that catalyses the breakdown of hydrogen peroxide (0) to water and oxygen in practically all living organisms exposed to oxygen. It is a crucial enzyme in the protection of the cell against oxidative damage caused by reactive oxygen species.
