Document Summary

cyclic amp: nucleotide secreted by single celled organism, slime mold. eventually run out of nutrients, secrete cyclic amp. cyclic amp attracts each other, so all mold gets together into a slug and move out of wood. this organism is at the edge of unicellular and multicellular. two types of cells stalk and spores spore flies away stalk dies. get together because they"re attracted to camp. cell migrates towards the source outside the cell. cell receives camp, activates pi-3 kinase: actin polymerases and pseudopods pushes out, so movement. hydrophilic ligands : can move around in extrcelluar fluid, or secreted from one cell and move by diffusion to another. cytosolic domain has enzymatic activity or is associated with an enzyme . or associated with an enzyme: (see the figure 15-16) built into receptor or not built into receptor. Important roles in animal development : extremely important, specifying cell types .
