Macromolecules Webquest Name-

Part A: What is a macromolecule? You can find the answers here

1. What are the four macromolecules?

2. What is a polymer?

3. List the monomers that are linked together to form each of the following macromolecules (what are the building blocks of each macromolecule): 1. Proteins: 2. Carbohydrates: 3. Nucleic Acids:

Part B: Why do we eat? Watch this video, and answer the following questions. If you miss something in the movie, the script is written out below. If you are unsure about some of the information, use the internet to find more info.

1. What did William Prout study? Why did he study this?

2. Why is glucose so important?

3. How is the way humans obtain and store energy different from plants?

4. What is the most common lipid?

5. Steroids are a type of what macromolecule?

6. What does it mean for a lipid to be saturated or unsaturated?

7. What are three types of proteins?

8. What are the building blocks of proteins?

9. Humans cannot produce all of the 20 amino acids necessary to produce proteins. How many amino acids can humans NOT produce? How do we get these?

Part C: Macromolecules in 3D Here you will browse through several 3D images of different macromolecules. Study the images to find features that you learned about in the previous tutorials.
