Lesson Plan Summary Sheet Teacher: Howerton Subject: Biotechnology 2 Topics: Unit B3: Proteins Date 10/27 Essential Question(s) How does the structure of proteins relate to its function? Activities □ View Proteins as Products Powerpoint □ Activity 5.1 Students will create informational posters about a given protein’s structure and function □ Lab11: The Action of Different Enzymes on Apple Juice Production Vocabulary Primary Secondary Tertiary Quaternary Learning Logs B31: Write a job description for the protein of your choice. Describe its structure and function. 10/28 What role do enzymes play in the cell? Enzyme Substrate Lock-and-key cellulase, pectinase, protease, rennin Kinetics Titrations B32:Explain what enzymes are and the factors that affect them. 10/29-30 What enzyme kinetics affect enzyme activity? □ View Enzymes powerpoint □ Lab 12: Enzyme Catalysis 11/2 How Do You Know When You Have Some Amylase? □ Lab14: Assaying for Amylase Activity Assay B33:Complete Lab13 : Developing an Assay for Protein Activity (Amylase) for homework B34:Explain the function of amylase. 11/3 Do any bacterial species have native amylase activity? □ Lab 15: Searching for Native Amylase Producing Bacteria Halos Native B35:Explain how you can test for amylase in bacteria. 11/4 How do you use the spectrophotometer to study molecules? Absorbance, OD, transmittance 11/5 How can you harvest amylase produced by bacteria? □ Lab 16: Using the Spectrophotometer to Study the Amylase Protein □ Lab 17: Harvesting Amylase from Bacterial Cultures 11/6 How can you change the buffer that a protein is in? □ Lab 18: Dialysis of Proteins into Different Buffers Dialysis B36:Explain why it is important to find the lambda max for a proteinreagent mixture? B37:Explain at what time during the growth of a bacterial culture is it best to harvest a protein? B38:Explain how dialysis works. 11/9 How do you use chromatography to separate proteins in a solution? □ Lab 19: Using Ion-Exchange to Purify Amylase from Broth Ion exchange chromatography Affinity chromatography Scale-up broth B39:Explain ion exchange chromatography □ Lab 20: Testing for the Presence of Protein in Solution □ Lab 21 Identifying Amylase using SDS PAGE Standard curve 11/12 How do you determine the amount of protein in a sample? How do you characterize proteins by PAGE? 11/13 What protein products are in the line? □ Activity 8.4: Product Pipeline Study varies 11/16 What techniques are used to manipulate proteins in a biotech lab? □ Review and wrap-up □ Protein Project Due none 11/17 What techniques are used to manipulate proteins in a biotech lab? □ Test on Unit □ Vocabulary and Learning Logs Due none 11/10 SDS, polyacrylamide Laemmli Buffer Denaturation B310:Explain how the Bradford assay works. B311: You run a gel from an ionexchange chromatography. You see 6 bands in the wash samples and 3 bands in the elution sample, including a band of 61kD. Has amylase been purified from the other proteins in the broth? What else can you do? B312:Report on a protein product of interest. B313:Explain how you plan to prepare for the test and whether you were successful. B314:Write a reflection on your effort and what you have learned this unit.
