Receptors
- Ionotropics
- The receiver is associated physically to an ion
channel
- Or form part of it
- Multimeric structure composed of several subunits
- Cholinergic receptor
- GABA Receptor
- Glycine receptor
- Glutamate
- NMDA
- AMPA
- Kainate
- Purinergic
- Activated by ATP
- Nicotinic
- It allows the passage of cations Na/k /Ca2
- Despolarization
- Acts as Activator
- The receiver allows the passage of anions Cl-/ HCO3
- Hyperpolarization
- Acts as inhibitor
- Ionic channel specific to certain ions
- Responds faster
- Metabotropic
- They are bonded to G proteins
- When the ligand binds to the receptor activates the G protein
- The protein activate other seconds messengers
- The messengers
- Activates genes
- Open ionices channels to produce
the response
- Responds more slowly
