Document Summary
Unit 3 - chapter 9 - 10/17 & 10/19. The signaling molecule is expressed/ presented on the cell surface of the signaling cell (a) That signal is then going to be recognized by a cell surface receptor on another cell (target cell) (b) Only see intracellular effects of signal/ receptor interaction when 2 cells are close. A signaling molecule is secreted/ excreted from the signaling cell. That signal binds to receptors on the signaling cell. A target cell is any cell that has a receptor for that specific signal. The signaling cell secretes a signaling molecule --> binds to receptors on neighboring cells, but does not affect signaling cell. Signaling cell is far away from target cell. Use some sort of transporting system to move these signals around. Interactions between cell surface proteins are a type of ________. Response to a signal is a three step process.
