effect of enzymes on a reaction

... What is the effect of Enzymes on a reaction? Introduction There are many factors which affect the rate of reaction; temperature, substrate concentration, enzyme concentration, ph and inhibitors. Catalase is a very fast acting and efficient enzyme, therefore making it ideal for my experiment. Catalase catalyses the decomposition of hydrogen peroxide (H2O2), into water (H2O) and oxygen (O2). One molecule of catalase can convert millions of molecules of hydrogen peroxide to water and oxygen per second. 2H2O2 2H2O + O2 Enzymes are catalysts and like all catalysts, enzymes work by lowering the activation energy, thus dramatically increasing the rate of reaction. Enzymes are not consumed by the reactions they catalyse, neither do they alter the equilibrium of these reactions. The enzyme catalase is found in microbodies or peroxisomes in eukaryotic cells. A main source for catalase is the potato tuber. Enzymes are very specific, and it was suggested by Emil Fischer in 1894,
