Unit Four : Protein Enzymes Inquiry

Directions: Answer the questions on a Google Doc. Work independently first, and later you will work in a group.

Engage : 1. Why do some people have difficulty drinking milk, and eating milk products like ice cream?

Explore: 2. Use the Web to find out what is meant by Lactose Intolerance. Collect information. You can paste information here, after each question:

a. What is the protein enzyme Lactase?

b. Where is it found, what does it do?

c. What is lactose?

d. Do a Google search for an image of molecule of the protein enzyme Lactase. Paste a picture of the Lactase Molecule here.

Explain: 3. Explain in your own words: What is the function of an enzyme?

Elaborate: 4. Review and Describe the structure of a Protein.

a. What is an amino acid?

b. HANDS-ON: Work with a partner to make a model of the amino acid :

One person make Alanine :

Another person make Glycine:

C. Place the two amino acids next to one another. This is the beginning of a protein structure. Explain how a protein is a polymer of amino acids:

Evaluate:5. Take this informal, Formative Quiz to see how much you have learned about Protein Function and Structure.
