Catalase on hydrogen peroxide
The aim of this study was to test the rate of reactivity of the enzyme catalase on hydrogen peroxide while subject to different concentrations of an inhibitor. The hypothesis was that hydrogen peroxide will be broken down by catalase into hydrogen and oxygen, where a higher concentration of inhibitor will yield less oxygen, resultant of a lower rate of reaction. Crushed potato samples of equal weight were placed in hydrogen peroxide solutions of various temperatures. The results showed that less gas was produced as the concentration of the inhibitor rose. This Is because more enzymes were inhibited, and so less active sites were available for reaction.

Anteprima della tesi: Catalase on hydrogen peroxide
Abstract The aim of this study was to test the rate of reactivity of the enzyme catalase on hydrogen peroxide while subject to different concentrations of an inhibitor. The hypothesis was that hydrogen peroxide will be broken down by catalase into hydrogen and oxygen, where a higher concentration of inhibitor will yield less oxygen, resultant of a lower rate of reaction. Crushed potato samples of equal weight were placed in hydrogen peroxide solutions of various temperatures. The results showed that less gas was produced as the concentration of the inhibitor rose. This Is because more enzymes were inhibited, and so less active sites were available for reaction. Reasearch and rationale Hypothesis: Catalase will break down hydrogen peroxide in water and hydrogen. A higher concentration of inhibitor will yield a slower rate of reaction, thus yielding less oxygen in a given time. Null hypothesis: Catalase will break down hydrogen peroxide in water and hydrogen. The concentration of the inhibitor will have no effect on the rate of this reaction. Supporting knowledge: Enzymes function as biological ...... of the Worldwide Protein Data Bank.
