What does the reaction controlled by catalase produce?

The reaction controlled by catalase produces oxygen and water. Catalase is an enzyme that catalyzes the breakdown of hydrogen peroxide, a toxic byproduct of cellular metabolism, into harmless substances. In this reaction, hydrogen peroxide (H2O2) is decomposed into water (H2O) and oxygen gas (O2). This is significant because it detoxifies hydrogen peroxide, preventing potential damage to cells and tissues. The release of oxygen gas during this process is a key characteristic of the action of catalase and serves as a rapid and efficient means of protecting the cell, especially in environments where hydrogen peroxide may accumulate.
