Document Summary
Cell communication and signaling lectures 15, and 16: chapter 11. Occurs within unicellular organisms such as bacteria/yeast: mating (yeast) 2 sexes (mating types a and a) which are haploid cells. To mate, they fuse together creating a diploid cell. Cells of mating types a and a release a and a mating factors, these then bind to specific receptors on cells of opposite sex. A cells bind a factor and a cells bind a factor. This binding causes the cells to fuse and form a diploid a/a cell. A and a factors are short peptide (about 12 amino acids) Occurs within a multicellular organisms such as neurons: local communication- occurs between cells that are close together. Paracrine- signals release into the extracellular fluid. All cells but are mostly recognized only by specific cells that contain receptors for that specific signal. These secretory vesicles contain signals that go towards the targeted cell.
