Open Response Practice #1


Directions: Write your answer on the pages following the question below.

Answers must be in essay form. Outline form is NOT acceptable. Labeled diagrams may be used to supplement discussion, but in NO case will a diagram alone be sufficient. It is important that you read each question completely before you begin to write.

  1. The effects of pH and temperature were studied for an enzyme-catalyzed reaction. The following results were obtained.









    1. How do (1) temperature and (2) pH affect the activity of this enzyme? In your answer, include a discussion of the relationship between the structure and function of this enzyme, as well as a discussion of how structure and function are affected by temperature and pH.


    3. Describe a controlled experiment that could have produced the data shown for either temperature or pH. Be sure to state the hypothesis that was tested here.
