ENZYME FUNCTION ACTIVITY

Objectives:

1. To understand how the structure of an enzyme determines its function.

2. To understand what is meant by substrate-specific.

Procedure:

  1. On a piece of paper, neatly draw and color a diagram illustrating an enzyme substrate complex. Your drawing may illustrate an enzyme performing hydrolysis or an enzyme performing dehydration synthesis. Your diagram should include a series of 3 pictures – one that illustrates the enzyme and reactants prior to them joining, one that illustrates the enzyme and reactants bonded as a complex, and one that illustrates the enzyme and products at the end of the reaction. Use colored pencils and color the enzyme one color, the substrate(s) another color, and the product(s) another color(s). Label the enzyme, substrate(s), product(s), active site, and where water is either added or released. Be creative!!!

2.After your diagram is complete, use your notes on enzymes to answer the following questions. Please answer the questions in complete sentences that re-state the question. Put your answers either below your drawing or on the back of your paper.

  1. What are 4 features common to all enzymes?
  2. What is meant by an enzyme being a catalyst?
  3. Describe activation energy?
  4. What is the active site of an enzyme?
  5. Is the reaction shown in your diagram representing dehydration synthesis or hydrolysis? Defend your answer.
  6. Think back to biochemistry. Give a specific example of the substrate(s) and product(s) inyour diagram.
