4.2 Introduction to Signal Transduction

 

Today's Learning Objective(s):

·       Describe the components of a signal transduction pathway.

·       Describe the role of components of a signal transduction pathway in producing a cellular response.

#	Tasks:
1	Quizlet Cell Communication         Practice the concepts from class this week. Not for a grade.
2	Video: Signaling Pathway Amoeba Sisters > Cell Signaling   Amoeba Sisters > Cell Signaling
3	Reading and Note-Taking 9.2 Propagation of the Signal & 9.3 Response to the Signal - Compete the packet.   The textbook does not include a section on cell signaling. This is an important topic in unit 4. We will use an online college text called Open Stax AP Biology.   9.2 Propagation of the Signal 9.3 Response to the Signal
4	Poster: Ligands   You are assigned a ligand (signal molecule). You will   research its properties, identify the signaling mechanism and range, and produce a simple flow chart showing how the signal is produced, transmitted, received, and the cellular response. Due end of the week.      See details on the document.
