BIO 1140 Lecture Notes - Lecture 12: Acetylcholine, Signal Transduction, Growth Factor
Document Summary
Readings: 43. 2, igure 38. 2, addiional in course resources. Intracellular, ion channels, enzymaic receptors (paricularly rtk/tyr-k), gpcr (camp and. Describe in detail an example of a cellular response with its signal transducion cascade. Recognize and describe the mechanisms (6) that can terminate a cellular response. By sending a chemical messenger that will trigger a signal transducion cascade. By sending a transcripion factor that will trigger a signal transducion cascade. Receptor acivaion leads to relaying and amplifying the signal inside the cell. Step 2: transducion internal receptor in nucleus then step 3 is response molecule in nucleus. Or step 2: transducion internal receptor in cytoplasm then step 3 is response molecule in cytoplasm or plasma membrane. Cell receptor needs to meet a receptor and bind to a receptor, once this happens there is a series of events inside the cell that orient the response the target cell takes depending on the message received.
