1. Regulation of ion channel
Presented by Bódis Viktor

2. Ion channel located within the plasma membrane
Pore-forming membrane protein
Functions:
Regulate the ion flow
establishing resting membrane potential
shaping action potential
Rate of ion transport is very high
Ion pass along contretracion gradient
Passiv transport
Ion channel classification by selectivity:
Selective
Less-selective
Non-selective

3. Classification by gating
Voltage-gated
Ligand/G-protein -gated
different concentration of ions on either side of the membrane.
binding of ligands/G protein to the channel

4. Voltage-gated ion channel
Triggered by changing ion contrentration
Act in propagation of action potential
Ball and chain inactivation

5. Neurotransmitter receptor
Ligand gated ion channel
Bind the neurotransmitter
Located at synapses
G protein-gated ion channel
Inhibitory/excitatory
