Post-Lab Questions
- What reaction is being catalyzed in thisexperiment?
- What is the enzyme in this experiment? What is thesubstrate?
- What is the independent variable in this experiment? What isthe dependent variable?
- How does the temperature affect enzyme function? Use evidencefrom your data to support your answer.
- Use Excel or another graphing program to create a graph of thechange in balloon circumference over time for each differenttemperature. Insert an image of your graph here.
- Why is measuring the changes in balloon circumference aneffective way to measure the activity of this specific enzyme?
- Is there a negative control in this experiment? If yes,identify the control. If no, suggest how you could revise theexperiment to include a negative control.
- In general, how would an increase in substrate alter enzymeactivity?
- Design an experiment to determine the optimal temperature forenzyme function, complete with controls. Where would you find theenzymes for this experiment? What substrate would you use?
