Enzymes are proteins that act as catalysts for biological reactions. In other words, they accelerate reactions. They are substrate specific, meaning that certain enzymes only bind at active sites of specific substrates (or a family of substrates), catalyzing specific reactions. There are many different classes of enzymes. For example, hydrolases catalyze the hydrolysis of a substrate through the addition of water and synthases catalyze the synthesis of a substance. Numerous factors can impact the enzymatic rate of reaction, including concentration, pH and temperature.

Activity Instructions:

Use the provided data to analyze the impact enzyme concentration has on the rate of reaction. Proper analysis will provide you with the appropriate information needed to write a results section and a discussion section for this data.

  • Prior to looking at the provided data, state your hypothesis. Do you predict that an increase in concentration will cause an increase or decrease in enzymatic rate? Be sure to write your hypothesis using complete sentences.
