How are metabotropic receptors inactivated

When an ionotropic receptor is activated, it opens a channel that allows ions such as Na +, K +, or Cl − 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 or other intracellular events, but involve a range of … Ver mais A metabotropic receptor, also referred to by the broader term G-protein-coupled receptor, is a type of membrane receptor that initiates a number of metabolic steps to modulate cell activity. The nervous system utilizes two types of Ver mais The G protein-coupled receptors have seven hydrophobic transmembrane domains. Most of them are monomeric proteins, although GABAB receptors require heterodimerization to function properly. The protein's N terminus is located on the … Ver mais Chemical messengers bind to metabotropic receptors to initiate a diversity of effects caused by biochemical signaling cascades.
