| Question |
Answer |
| Receptor |
a cellular factor that recognizes and binds a specific ligand to induce a response |
| Ligand |
a molecule bound by another molecule such as a receptor |
| Intercellular Signaling Molecule |
nutrient ligand secreted by one cell to induce a response in another cell |
| Hormone |
intercellular signaling molecule that controls metabolism or physiology |
| Growth factor |
intercellular signaling molecule that controls cell cycle progression, cellular differentiation, or morphogenesis during development |
| Cytokine |
growth factor involved with hematopoiesis |
| Isoreceptors |
different receptors bound and activated by the same ligand, often inducing distinct responses in different cells |
| Paracrine |
for an intercellular signaling molecule to diffuse over a short distance, usually through interstitial spaces, to induce a response |
| Endocrine |
for an intercellular signaling molecule to diffuse through the blood |
| Hydrophobic Ligands |
Steroids (cholesterol derivatives)
Fatty acid derivatives (prostoglandins, retinoic acid)
|
| Hydrophilic Ligands |
Amino acid derivatives (catecholamines-tyrosine, histamine-histidine, serotonin-tryptophan)
Peptides and proteins (insulin, glucagon, FSH, TGFβ, etc.)
Nucleotides (cAMP)
