Q

Elektrische synapsen

A

Werken via gap junctions.
- Veel ionen
- Weinig selectief
- Niet uitputbaar
- Slechte remming

Q

Aminozuren neurotransmitters (4)

A
  • Glutamaat
  • Aspartaat
  • GABA
  • Glycine
17
Q

Biogene aminen neurotransmitters (5)

A
  • Adrenaline
  • Noradrenaline
  • Dopamine
  • Serotonine
  • Histamine
18
Q

Neuropeptiden

A

Endorfine

19
Q

Domeinen kernreceptoren (5)

A
  • Hormoonbinding
  • DNA binding
  • Dimerisatie
  • Co-activator/co-repressor
20
Q

2 Soorten receptoren

A
  1. Cell-surface
  2. Intracellulair (kernreceptoren)
21
Q

Affiniteit

A

Mate waarin een hormoon aan de receptor bindt

22
Q

Kd

A

Bindingsconstante, heel laag

23
Q

5 stappen G-eiwit gekoppelde receptoren

A
  1. Ligandbinding, GDP aan a-unit wordt GDP
  2. G-proteine laat helemaal los van receptor
  3. a-GTP en Bg-units laten van elkaar los
  4. a-GTP en Bg binden aan hun respectieve effectors
  5. a-unit hydrolyseert GTP tot GDP en inactiveert zichzelf, promoot herbinding tot G-proteine en aan receptor
24
Q

Domeinen membraanreceptoren (3)

A
  1. Hormoonbinding
  2. Transmembraandomein
  3. Tranductiedomein
25
Q

3 Soorten membraanreceptoren

A
  1. Ionakanalen
  2. Enzymgekoppelde receptoren
  3. G-eiwit gekoppelde receptoren
26
