STATION 6 “Enzymes”:
Define the following terms:
A. Enzyme: _______________________________________________________________________________________
B. Catalyst: _______________________________________________________________________________________
C. Substrate: ______________________________________________________________________________________
D. Active Site: _____________________________________________________________________________________
E. Activation Energy: _______________________________________________________________________________
Procedure:
1) Using the paper provided, you will make an enzyme puzzle. You need to create a substrate, an enzyme with a
matching active site, and products that are formed after the enzyme speeds up the reaction. If you have problems, refer to
page 159-160 in your biology book.
2) You will have to name your enzyme. Usually, enzymes end in ‘ase.” For example, catalase is an enzyme used
frequently in the lab. Write the enzymes name on the paper.
3) Then, make sure to label each piece of your puzzle. If for example you have the substrate piece, label it SUBSTRATE.
All pieces need to be labeled in order to get full credit.
4) Then, create a competitive inhibitor that may fit in the active site of the complex, but will not allow the reaction to start.
5) Lastly, answer the analysis questions below using complete sentences.
Analysis: Answer using complete sentences.
1) What did you name your enzyme? Why? ______________________________________________________________
2) What type of macromolecule is an enzyme? ___________________________________________________________
3) Why is the enzyme-substrate complex compared to a “lock and key?” Explain. (HINT: try to incorporate the words
“specific” and “re-usable” when explaining)
4) Why do competive inhibitor molecules slow down reaction rates?
5) What other types of environmental conditions may slow down or denature an enzyme?
6) How do enzymes work? (HINT: what do they lower to make the reaction occur at a faster rate?)
7) Enzymes can build up molecules and they can also break down molecules. These bonds of the molecules are made
during CIRCLE (dehydration synthesis or hydrolysis reactions) and are broken during CIRCLE (dehydration synthesis or
hydrolysis reactions).
