Answer :
Final answer:
Catalase is an enzyme in potatoes that transforms harmful hydrogen peroxide into water and oxygen. This can be observed in a lab as fizzing or bubble formation, which is the oxygen being released. Without enzymes such as catalase, biological systems couldn't function effectively.
Explanation:
In the context of a potato enzyme lab, catalase is an internal enzyme found in the potato which plays a significant role in converting harmful hydrogen peroxide (H₂O₂) into safer substances: water and oxygen. This transformation is represented by the chemical equation 2H₂O₂ → 2H₂O + O₂. In other words, the catalase acts as a catalyst to speed up this chemical reaction without itself being consumed or altered, therefore it is reusable.
So how do you know that catalase has done its job? In a typical lab setting, this might be observed as a fizzing effect or bubbles forming - this is quite literally the oxygen being released in the reaction.
Thus, enzymes such as catalase are essential to life systems. Without them to facilitate and speed up chemical reactions, biological systems, much like sluggish laptops, would be nonfunctional.
