Metabotropic receptors

Metabotropic receptors are a type of protein found on the surface of cells, particularly in the nervous system. Unlike ionotropic receptors, which directly open channels to allow ions into the cell, metabotropic receptors work through a more indirect method. When a molecule, like a neurotransmitter, binds to them, it triggers a series of biochemical events inside the cell using secondary messengers. This process can lead to various effects, such as changing the cell's activity over time. Essentially, metabotropic receptors help regulate cellular responses and communication in a more complex way than just opening doors for ions.
