BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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-2: -Answer and Explanation: A potato contains a enzyme called catalase. Catalase speeds up the decomposition of hydrogen peroxide (H2O2 H 2 O 2 ) into water and oxygen (which forms the bubbles) as the reaction happens very slowly at room temperature.

Detailed explanation-3: -Catalase, an enzyme found inside a potato, breaks down hydrogen peroxide into water and oxygen gas. The advantage of this reaction is that you can see the oxygen gas bubbling out as it is formed so you can tell how fast the reaction is happening.

Detailed explanation-4: -The frozen potato should have produced fewer bubbles than the room temperature sample because the cold temperature slowed the catalase enzyme’s ability to decompose the hydrogen peroxide. The room temperature potato produced the most bubbles because catalase works best at a room temperature.
