BIOL&211 - (Chapter 11) Cell Communication [Page 2]

Cell Signaling -Discuss the differences between local signaling and long-distance cellular communication -Describe the three stages of cell signaling. Receptor Proteins -Know what receptor proteins are, where they are located, and what they do -Know the three cell surface receptor superfamilies, the basic structures of each and how each functions to convert an extracellular signal to an internal one. -Differentiate between intracellular receptors and cell surface receptors in terms of function. Signal transduction -Describe the significance of cAMP and calcium as second messengers -Explain the amplification process associated with protein kinase cascades. Apoptosis -Define apoptosis and its importance. Differentiate it from necrosis. -Relate apoptosis to cell signalling and the cell cycle
