Reactions Get a Boost Abstract: The cells can perform many chemical reactions because of enzymes which catalyze them. A change in temperature will denature the enzyme and slow the reaction. The end product of this experiment is the red-brown substrate which is our visible marker that the reaction happened. We mixed the enzyme (peroxidase) with the substrate and inserted it into the spectrophotometer to measure the rate of absorbance. The control in this experiment is the hydrogen peroxide and the guaiacol together which make peroxidase. Introduction: Cells perform multiple chemical reactions rapidly because of enzymes, which act as catalysts to speed up chemical reactions. They lower the free energy of activation without being consumed or altered. The substrate is the material the enzyme reacts with and the active site of the enzyme and catalysis takes place. Peroxidases normally convert toxic hydrogen peroxide, produced by several metabolic reactions into water and oxygen. They are known to play a role in the plant’s defense against pathogens.
