Structured Notes for Signaling Molecules and Cellular Receptors
A scan-friendly outline of Biology 2e 9.1 organized around Signal, Found in Multicellular Organisms, Ligand.
- Communication between cells is called intercellular signaling, and communication within a cell is called intracellular signaling.
- Track the section's working concepts: Signal, Found in Multicellular Organisms, Ligand, Signals.
- Use the outline to move from textbook wording into recall-ready relationships.
Key takeaways
- Communication between cells is called intercellular signaling, and communication within a cell is called intracellular signaling.
- Chemical signals are released by signaling cells in the form of small, usually volatile or soluble molecules called ligands.
- Ligands interact with proteins in target cells, which are cells that are affected by chemical signals; these proteins are also called receptors.
