Document Summary
Textbook reference: chapter 9 in biology how life works (2nd ed. ) Sections 9. 3 to 9. 5; pp. 185 to 194. Required textbook readings (use the headings below to make notes on these readings: section 9. 1 principles of cell communication (pp. 180 to 182, section 9. 2 types of cell signaling (pp. Coordinates activities within the cell (since there are so many cells performing different functions at the same time) Allows cells to respond to their environment and to influence the behavior of other cells. Communication happens through chemical signals, specific to the receptors they bind to. Signals can come from outside the organism. Adrenaline is able to act upon many organs. Adrenaline then interacts with receptor proteins on responding cells within the heart and other organs which bacteria are able to determine whether they are at a high or low population density. With this information, they can turn on specific genes that control antibiotic resistance and other activities.
