Chapter 11: Cell to Cell Communication

Today students had a quiz on sections 11.1 and 11.2.

By the end of today students should feel somewhat confident in their abilities to:

1. Describe the basic signal-transduction pathway used for mating in yeast.
2. Define paracrine signaling and give an example.
3. Define local regulation and explain why hormones are not local regulators.
4. Explain how plant and animal hormones travel to target cells.
5. List and briefly define the three stages of cell signaling.
Signal Reception and the Initiation of Transduction
6. Describe the nature of a ligand-receptor interaction and state how such interactions initiate a signal-transduction system.
7. State where signal receptors may be located in target cells.
8. Compare and contrast G-protein-linked receptors, tyrosine-kinase receptors, and ligand-gated ion channels.

Homework: Read 11.3 and 11.4 As far as taking notes: notes are designed to HELP you. If taking notes helps you, TAKE NOTES. If taking notes doesn't seem to do much good, don't take notes. You know what type of learning style you have, WORK WITH IT.
