Which of the following is not a G-protein coupled receptor? Explanation: Glycine receptor is a neurotransmitter but not a GPCR. Explanation: Protein kinase A is activated when cAMP allosterically binds to a regulatory peptide.

What do serotonin blockers do?

SSRIs treat depression by increasing levels of serotonin in the brain. Serotonin is one of the chemical messengers (neurotransmitters) that carry signals between brain nerve cells (neurons). SSRIs block the reabsorption (reuptake) of serotonin into neurons.
