Ligand-Gated
Ion Channel Receptors
They
are found in excitable tissues such as nerves, muscles or heart.
There function is mainly to regulate the entry of ions or
electrolyte in the cell. The only way to open up the channel is
through binding of the drug into the receptor.
G-
Protein Receptors
Function
is to regulate the stimulation or suppression of normal processes in
the body that when a drug is bound into the receptor such as
increase of heart rate, inhibition of secretion of saliva and alike
are produced.
Intracellular
Receptors
Receptor
for hormonal functional. Examples are Estrogen and Thyroxine
Tyrosine
Kinase Receptor
Located
in the plasma membrane. Main function is for cell growth.
