4.3 Changes in Signal Transduction continued

 

Today's Learning Objective(s):

·       Describe the different types of cellular responses elicited by a signal transduction pathway.

#	Tasks:
1	Quizlet Blast – Changes to Signaling Pathways Let’s revisit the recent vocabulary. Practice makes permanent!
2	Protein-Kinase Pathway Examples   Yesterday, you and your group researched a ligan, receptor, and a pathway using protein kinases to elicit a cellular response. Let’s see what you created!
3	Graphic Organizer – Agonists and Antagonists   Agonists activate receptors, mimicking natural substances to produce a biological response, while antagonists block receptors, preventing activation and reducing a substance's effect.   Use the graphic organizer and internet resources to add detail to the graphic organizer.
4	Notes > Changes in Signal Transduction   Let’s look at the role of changing cellular communication using a variety of methods.
5	Modeling and Examining Mutations in a Signal Pathway   Create a model showing a specific mutation in the EGF signaling pathway.
