Q

Schlüssel Schloss Prinzip

A

Transmittermoleküle binden and spezifische Rezeptoren

Schloss: Rezeptor = Protein an dem Liganden binden und Reaktion auslösen

Schlüssel: Ligand = Substanz, die RT bindet

17
Q

Ionotrope Rezeptoren

A

-Transmitter bindet direkt an Rezeptor
- Verändert Form des Rezeptors
- Öffnet/ Schließt Ionenkanal
-> schnelle Wirkung

18
Q

Metabotrope Rezeptoren

A

First Messenger: T bindet an Rezeptor
- Alpha Untereinheit trennt sich vom G-Protein
- Moduliert Aktivität Zielmoleküls

Zielmolekül: Ionenkanäle/ Second Messenger
