Using Diabetes as the Story to Discuss the Secretory Pathway of Proteins

Written by Kelly A. Hogan, University of North Carolina at Chapel Hill

Learning Outcomes:

– To use insulin as an example secretory protein

– To examine an analogy that the cell is a protein factory analogous to a manufacturing factory

– To learn about an important disease students may know little about

Activity Description: Students act out an interpreted case study and discuss answers to the questions. Lecture or animations may be interspersed in the discussion.

Time Needed: Approximately 50 minutes

Materials Needed: Copies of the case study and questions, 3 x 5 index cards

Activity Instructions: Choose 6 students to play the roles. Intersperse lecture, BioFlix animations, and discussion as needed. I always play the role ofLena, so that I can still play a “teaching role” and pull up animations while I say my lines.

OPTIONAL: The animation that could be shown to the class is located at:

For question 8, I have my students write their answers on 3 x 5 index cards. I ask them to swap cards several times with classmates. When I ask for people to read from their cards, I get a much better response. We then discuss whether the analogy is a good one or not.
