Document Summary
Each sex of yeast releases a chemical that is only recepted by the opposite type. Once this has attached, they release another chemical that causes them to mate (join) Bacteria and quorum sensing can give off signals to other bacteria when something like a nutrient is scarce so they can protect themselves in a biofilm. Local signaling cell junction where cytoplasm can send signaling substances through cytosol. Paracrine signaling sends out growth factors to stimulate growth synaptic signaling, travels through synapse. Endocrine signaling: hormones, specialized hormones travel through circulatory system until the target cells that have the receptor have been reached. A signaling molecule binds to a receptor protein, causing it to change shape. Signaling molecule is a ligand: molecule that specifically binds to another molecule. They typically cause the receptors to change shape and trigger a response. Gpcrs (g protein coupled receptors): cell surface transmembrane receptor that works with a g protein.
