Context of the Teachable Unit General biology major’s class (cell biology section) Target class size is 60 students, with 10 working groups of 6 students each Co-requisite coursework: general chemistry A one semester course, 2 lectures at end of the semester. 5 hours class time total, 10 hours out of class time.

Learning Goals Students should understand 1.How a signal is transduced, relayed, and amplified to lead to a biological response. 2.The regulation and termination of a biological signal and response in normal and diseased states. 3.How cell signaling regulates homeostasis.

Tidbit Objectives Students should be able to: 1.Describe how a message is communicated. 2.Diagram a signaling pathway. 3.Predict how disturbing the components of the pathway will affect cell signaling response.

Prior Knowledge Gained Cell signaling terms – Protein-protein interactions – Receptor – Ligand and how it interacts with receptors – Signal relay and response Cell membranes are selectively permeable Extracellular signals elicit cellular responses Basics of regulation

Diversity of People with Diabetes

Clinical Scenario In diabetes the response of one important pathway is to transport glucose from the extracellular fluid (ECF)/blood into the cytosol of cells. This pathway becomes disrupted as part of diabetes.
