Question

scenario 4: a student is conducting a lab experiment to study the enzyme catalase, which is found in living tissues like potatoes and breaks down hydrogen peroxide (h2o2) into water (h2o) and oxygen (o2). the student places a small piece of potato (containing the enzyme) into a beaker of hydrogen peroxide. she observes that the mixture begins to bubble vigorously as oxygen gas is released. after the reaction is complete, she finds that the potato piece is unchanged. in this experiment, what is the role of the enzyme catalase? it is a biological catalyst, which speeds up the reaction without being used up it is an inhibitor, which slows down the reaction it is the substrate, which is a molecule that is changed by the reaction it is a product, which is formed at the end of the reaction

Explanation:

Enzymes are biological catalysts. Catalase in the potato speeds up the breakdown of hydrogen - peroxide into water and oxygen without being consumed in the reaction, as evidenced by the unchanged potato piece after the reaction.

Answer:

It is a biological catalyst, which speeds up the reaction without being used up
