The Effect of Temperature on Rate of Enzyme Activity of Different Enzymes
Abstract/Purpose:
The main objective of this experiment was to determine how different factors, such as the type of enzyme and the temperatures that each of the enzymes were exposed to, could affect the rate of enzyme activity. In order to measure this, a potato enzyme and liver enzyme were placed in four different temperatures for 24 hours. Each enzyme was then placed in a test tube with hydrogen peroxide and the rate of enzyme activity was measured. The result was that the rate of enzyme activity decreased as the temperature increased for the liver enzyme, but increased for the potato enzyme.
Introduction/Hypothesis:
An enzyme is usually a protein that works as a catalyst, which is anything that helps to speed up, or catalyze, the chemical reaction (Bolster&Moss, n.d.). To speed up a chemical reaction, enzymes lower the activation energy, which is the initial energy required for a reaction to occur by applying heat. However, enzymes are very substrate-specific, only acting on specific reactants, which are the substrates, and consequently, enzymes are selective in the chemical reactions that they catalyze. Since an enzyme is a protein, each enzyme has a specific amino acid sequence, which determines its shape and eventually, the reactions that it will catalyze. In this way, an enzyme supports the biological theme that form fits function. Each substrate binds to the enzyme
