Potato Catalase Experiment

How it Works

When hydrogen peroxide (H2O2) comes in contact with an uncooked potato, a fascinating reaction occurs due to the presence of an enzyme called catalase in the potato. Catalase is abundant in living organisms, including plants, and it helps break down hydrogen peroxide into water (H2O) and oxygen (O2) gas. This enzyme speeds up the decomposition of hydrogen peroxide into its constituents, creating bubbles of oxygen gas that you observe as foam. However, in a cooked potato, the high temperature from cooking denatures the catalase enzyme, rendering it inactive. As a result, the cooked potato doesn’t produce the same bubbling reaction with hydrogen peroxide as the enzyme responsible for catalyzing the breakdown of hydrogen peroxide has been altered and can no longer facilitate the reaction.
