10-4-14 Per. 5 Reaction Rates of Enzyme Catalase Abstract Catalase is a helpful enzyme in many organisms. It reacts when put in certain environments or mixed with certain solutions. The question at hand is what kinds of variables will make the enzyme react either faster or slower; essentially, what variables will make the reaction rate of catalase change. After adding factors such as hot water, acid, or hydrogen peroxide the results were somewhat predictable, the greatest reaction was found when the catalase was mixed with hydrogen peroxide, and on the other hand didn’t have any reaction to any variable with a lower pH level like water. Introduction An enzyme is a catalyst causing a reaction to occur much faster than it would on its own. Enzymes lower activation energy required for a transition. A substrate is the specific reactant the enzyme affects. The enzyme catalase is found in almost all living things. It gets water and oxygen out of hydrogen peroxide which can be found in foods such as cheese and milk. The question at hand is the reaction to the enzyme in accordance to adding different abiotic factors. The reaction rate of the enzyme can vary and by adding different factors the rate of reaction can either increase or have no reaction at all. Knowing this could help to understand how the body may react…show more content…
However, only certain factors increased a reaction, while others did not have a reaction. Among the factors that increased the decomposition rates was the most reactive one, 2X H2O2 . So the purpose of the experiment was to show the rates of reaction when different pH variables , temperature, and solutions were added. After testing all of those factors the results were clear that the most reactive was the hydrogen peroxide, this makes sense as the enzyme catalase helps the body by breaking down hydrogen
