Lecture 9: Cell Signaling Part 1 Cell death signaling pathway https://www.cellsignal.com/  Lecture 9: Cell Signaling Part 1 Cell division Development Cell growth Cell death signaling pathway  Today’s agenda - A quick revisit of receptor-mediated endocytosis - Cell signaling 101 - Cell signaling pathways - Molecular switches What coat proteins function in recycling receptors to the plasma membrane? similar to Figure 15-33  Different coats are used for different steps in vesicle transport Still a matter of debate! ARROWS secretory pathway endocytic pathway retrieval pathway  How does the neutrophil “sense” the bacterium? and once it does How does sensing the bacterium lead to changes in the cell’s behavior?  The BIG questions of cell signaling: How do cells communicate? How are signals sensed? How is the information in a signal translated into action?  Signal transduction is the process by which one type of signal is converted into another Figure 16-2  Cells use extracellular signal molecules to communicate with one another in various ways long distance local long distance through most intimate, networks of short range neurons
