Exercise 1: Graphing and Analyzing an Enzymatic Reaction
During the course of an enzymatic reaction, the substrate (reactant) is converted to new and different products. The following data shows the amount of product that is produced over time.
Graph the data in the space provided below:
  •  Determine what variable to place on the x-axis and the y-axis.
  •  Label each axis in the provided text boxes.
  •  Scale each axis appropriately. Fill in scale values in the provided text boxes.
  •  Title your graph in the provided text box.
  •  Plot points as accurately as possible. You have been provided with a couple of points to get started - copy and paste these to create as many points as you need. Drag and drop them onto your graph. Draw lines to connect the points. You can draw a line by going to Insert >> Line >> Line. You can adjust the weight of your line by selecting it and adjusting line weight in the toolbar.

6. Notice on the graph that the time period between 0 and 3 minutes forms a straight line on the graph. What does this indicate about the rate of the reaction?
 
Calculating the Rate of Reaction.
Use the equation:   or  
 
The rate of an enzyme-catalyzed reaction can be measured to determine how fast the enzyme is converting substrate into product. A "rate" is the speed at which something occurs during a certain time period. To determine the rate of reaction, pick any two points on the curve. Divide the difference in the amount of product formed between these two points by the difference in time between them.
7. Calculate the initial rate of the reaction. The initial rate is the time between 0 and 1 minute.
 
8. Calculate the rate of reaction between 2 and 3 minutes.
 
9. How does the reaction rate between 0 and 1 minute compare to the reaction rate between 2 and 3 minutes?
 
10. Does your answer in question 9 agree with your answer in question 6?
 
11. In a graph of an enzymatic reaction, explain why the line begins as a straight line.
 
12. As seen on the graph, what happens to product formation between 3 and 6 minutes? Explain what is happening in the reaction at this point.
 
13. What is the rate of reaction after 6 minutes? Show the calculation for this.
 
14. As seen on the graph and by your calculation above, what happens to the reaction rate after 6 minutes? Explain what is happening in the reaction at this point.
 
- the variable on the x axis is time and the variable on the y axis is the amo...
