Protein Building Activity and PowerPoint Lab
Regular Bio – 2-3 partners
Slide #1 – Names, Period, and a Title
Vocabulary: Slide #2 with Definitions (include any sources you use on this page)
Protein
Enzyme
Denature
Amino Acid
Peptide Bond
Catalyst
Directions:
1. Cut a strip of paper 60 cm long X 3 cm wide
2. Draw lines every 2 cm. Example:
3. Color the blocks randomly with four different colors.
4. Make a globular protein and create a PowerPoint for this lab.
a) Hold the strip of paper at each end, this represents primary structure. Slide #3 - Take a picture and post
it in a PowerPoint with the slide labeled Primary Structure. In the PowerPoint, explain what Primary Structure
means.
b) Gently twist the strip a half turn to demonstrate secondary structure. Slide #4 - take a picture, post and
label the slide Secondary Structure. In the PowerPoint, explain what Secondary Structure means.
c) Bend the strip until 2 similar colors (amino acids) are touching and then staple or tape (hydrogen
bonding) them together to demonstrate tertiary structure – repeat 2x. Slide #5 - take a picture and post in a
PowerPoint slide. Label and explain.
d) Four students bond their individual amino acid chains (the strips of paper) together to demonstrate
quaternary structure. Be sure to link the structure at similar colors. Take a picture of your giant protein. Slide #6 Post in a PowerPoint slide, label and explain quaternary structure.
You now have a globular protein! Hang it in the classroom!
Slide #7 - answer the Analysis Questions:
1. What do the colored blocks represent?
2. What did you do to demonstrate the secondary structure of protein?
3. What types of bonds are formed during the tertiary level of structure?
4. What did you do to form the quaternary structure of a protein?
5. What kinds of conditions may cause a protein to denature? Would the protein still function after this change?
Why not?
6. Why is the biological concept of “Structure and Function” extremely important to building proteins?
Slide #8 – Pick any protein found in the body. The title should be the name of the protein you chose. Find a picture
of it and post on the slide. Answer the following questions:
a. How many amino acids long is your protein?
b. What does your protein do for the body? Job and what body systems are involved
c. Are there any diseases or disorders associated with your protein? (For example, what happens if
someone is born without that specific protein?)
