Bitter sensations are coupled to G protein-coupled receptors, which trigger internal calcium release, leading to neurotransmitter release.
Les sensations amères sont couplées aux récepteurs couplés aux protéines G, qui déclenchent la libération interne de calcium, entraînant la libération de neurotransmetteurs.
| Front | What chemical activates the bitter cell? |
|---|---|
| Back | 1. Bitter sensations are coupled to membrane receptors coupled to G proteins 2. G proteins called gustducins, in turn, trigger 2nd messenger systems 3. 2nd messengers trigger internal release of Ca+ which triggers release of NT to trigger NT VII and IX and X |
