KEY TAKEAWAYS •

Cell signaling can involve cell to cell connections, paracrine, autocrine, or endocrine signaling.

Ligands can be extracellular or intracellular, depending on where they bind. The most hydrophobic ligands will be intracellular.

Signaling pathways can turn on genes, turn off genes, affect cellular metabolism, or affect transcription.

Calcium, phosphatidyl inositol, and cyclic AMP are common intracellular second messengers.

G protein-coupled receptors are a large family of receptors that involve many different activities in eukaryotic cells only.
