Detailed explanation-1: -The enzyme known as ‘catalase’ is involved in the breakdown of hydrogen peroxide molecules into separate water and oxygen molecules. During this reaction, what happens to the ‘catalase’? The enzyme would be fully used up and discarded. The enzyme would remain unchanged in any way.
Detailed explanation-2: -When the enzyme catalase comes into contact with its substrate, hydrogen peroxide, it starts breaking it down into water and oxygen.
Detailed explanation-3: -Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals) which catalyzes the decomposition of hydrogen peroxide to water and oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS).
Detailed explanation-4: -Catalase breaks down two hydrogen peroxide molecules into one molecule of oxygen [9] and two molecules of water in a two-step reaction [10].
Detailed explanation-5: -2H2O2(aq)—-(catalase)—> 2H2O (l) + O2 (g) Figure 1. The decomposition of hydrogen peroxide to water and oxygen, as catalyzed by catalase.
