Metabotropic receptor is a subtype of membrane receptors at the surface or in vesicles of eukaryotic cells. In the cardiac system, based on their structural and functional characteristics, neurotransmitter receptorbiochemistry receptors can be classified into two broad categories metabotropic and ionotropic receptors. In contrast to the latter, metabotropic receptors do not form an ion channel pore rather, they are indirectly linked with ion channels on the plasma membrane of the cell through signal transduction mechanisms, often G protein s. Hence, they are a type of G protein coupled receptor . Others are Receptor tyrosine kinase tyrosine kinases or guanylyl cyclase receptors. What both receptor types have in common is that they are activated by specific neurotransmitters . When an ionotropic receptor is activated, it opens a channel that allows ions such as Na sup sup , K sup sup , or Cl sup sup to flow. In contrast, when a metabotropic receptor is activated, a series of intracellular events are triggered that can also result in ion channels opening but must involve a range of second messenger chemicals. Examples This class of receptors includes the metabotropic glutamate receptor s, muscarinic acetylcholine receptor s, GABA B receptor GABA sub B sub receptor s, and most serotonin ... 550 amino acids.
