    Abstract Enzyme catalysis was observed in order to analyze how changes in temperature, pH, enzyme concentration, and substrate concentration affected an enzyme-catalyzed reaction. This experiment analyzed the rate of enzyme-catalyzed reactions and observed the correlation between catalase activity and products formed. It was found out that the rate of an enzyme-catalyzed reaction starts off rapidly, decreases, and levels off or completely stops, and can be further affected by environmental factors...

    Introduction Enzymes are proteins produced by living organisms to speed up the rate in which chemical reactions occur. This process can happen fast, slowly, or stop the chemical reaction all together depending on the temperature, pH and concentration. Catalase is one of the most common enzymes. It is found in living organisms and is used to break down hydrogen peroxide. This must happen because hydrogen peroxide is considered toxic to cells in the body. However, when catalase is used it breaks...

    Potato Enzyme Lab INTRODUCTION An enzyme is a protein that speeds up or slows down a specific chemical reaction in an organism. A good rule of thumb is to remember that enzyme names end in “-ase”. This will help in identifying enzymes in further readings. Generally enzymes are catalysts. Hydrogen peroxide is a toxic chemical that is produced in many organisms during metabolism. Organisms must get rid of this toxin to survive. One reaction turns the hydrogen peroxide into water and oxygen. The...

A catalyst is a substance that speeds up chemical reactions without being consumed in the process. (Giuseppe, M 2002, p.69). After a reaction has been catalyzed, the catalyst can be used again to catalyze the same reaction. Enzymes reduce the activation energy (minimal energy) it takes for a reaction to take place.

    Introduction Enzymes are catalytic proteins. The purpose of a catalyst is to speed up metabolic reactions by lowering the free energy of activation or activation energy. Activation energy is known as the amount of energy needed to push the reactants over an energy barrier, so that the downhill part of the reaction can begin (Campbell 151). In an enzyme catalyzed reaction, the enzyme binds to its substrate, which is the reactant an enzyme acts on. In the reactions, the enzymes are very specific...

    Enzyme Reaction to Variable Elizabeth Alvidrez University of Texas at El Paso Abstract: An enzyme is a protein that serves as a biological catalyst (Denniston, 2007). Metabolic reactions happen with in cells. Enzymes are proteins that are used to speed up these reactions without being consumed by them (Mader, 2010). Catalase is a catalyst that digests potent hydrogen peroxide and converts it into H2O and O (Campbell Reese, 2008). The environment plays an important role...

    Introduction This experiment is designed to test the enzyme activity of Catecholase the enzyme in potato juice, in many different conditions such as varying temperatures, ranging pH, and concentration of the enzyme, as well as concentration of the substrate. Most reactions are very slow; enzymes are used to speed up reactions. Enzymes have an active site that a substrate attaches to, but changes temperature, pH, and concentration can alter the active site (Helms, 1998). Organisms have a specific...
