CB1 and CB2 receptors mediate the effects of cannabinoids. What type of receptors are they?
Understand the Problem
The question is asking about the classification of cannabinoid receptors, specifically CB1 and CB2 receptors. It requires identifying the receptor type based on the provided options, which include ligand-gated ion channels, G-protein coupled receptors, receptor tyrosine kinases, and voltage-gated calcium channels.
Answer
They are G-protein coupled receptors (GPCRs).
CB1 and CB2 receptors are G-protein coupled receptors (GPCRs).
Answer for screen readers
CB1 and CB2 receptors are G-protein coupled receptors (GPCRs).
More Information
G-protein coupled receptors are the largest family of cell surface receptors. They activate intracellular signaling pathways in response to extracellular signals.
Tips
It is important to remember the longer name of GPCRs (G-protein coupled receptors), as scientists may use this name instead of the abbreviation.
