This is a 6-page graphing activity for students on enzymes and reaction rates of reactions that occur within living cells. This activity serves the dual purpose of reinforcing concepts about enzymes as well as an "always needed" review of graphing. The student will complete 3 separate graphs. Critical thinking and thought provoking questions follow each graph.
The activity begins with the student answering 5 questions concerning the nature of enzymes. It is assumed that the instructor will have already taught a lesson on enzymes. This introduction is followed by three graphing exercises:
Exercise 1: Graphing and Analyzing an Enzymatic Reaction
The student is given data on the amount of product produced over time during an enzymatic reaction. The student will graph the information, and calculate the rate of reaction at various time intervals. There are 9 follow-up questions in this section.
Exercise 2: The Effect of Temperature on Enzyme Functioning
The student is given data on the reaction rate of an enzyme-catalyzed reaction taking place over a range of temperatures. The student will complete the graph and answer 6 questions.
Exercise 3: The Effect of pH on Enzyme Functioning
The student is given data on the reaction rate of an enzyme-catalyzed reaction taking place over a range of pH levels. The student will complete the graph and answer 5 questions.
The 6-page student activity is set up so that students can graph and answer the questions directly on the handouts. Grids are provided for graphing. To save paper you can easily print a classroom set and have students complete the work on their own notebook paper and graph paper.
This document also includes a very detailed 5-page teacher answer guide.
This activity has served me well as a homework assignment, test review or classroom work. I often keep a copy of this in my emergency sub folder. It makes a great activity for students to complete in my absence.
This activity was written for my high school biology classes. It is appropriate for all biology and life science classes in grades 9 through 12.
You will receive both a Word document as well as a pdf of this activity.
