The series of molecular signals generated as a consequence of a serotonin receptor binding to its physiological ligand, where the pathway proceeds with inhibition of adenylyl cyclase and a subsequent decrease in the concentration of cyclic AMP (cAMP).

The series of molecular signals generated as a consequence of octopamine or tyramine binding to a cell surface receptor. Octopamine and tyramine are decarboxylation products of tyrosine, and are the invertebrate counterparts of the vertebrate adrenergic transmitters.

The series of events required for an organism to receive an olfactory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Olfaction involves the detection of chemical composition of an organism's ambient medium by chemoreceptors. This is a neurological process.

Any process that modulates the frequency, rate or extent of adenylate cyclase (AC) activity that is an integral part of a G protein-coupled receptor signaling pathway.

Any process that activates or increases the frequency, rate or extent of phospholipase C-activating G protein-coupled receptor signaling pathway.

The series of molecular signals generated as a consequence of a serotonin receptor binding to one of its physiological ligands.

Any process that stops, prevents, or reduces the frequency, rate or extent of the regulated release of serotonin.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an alkaloid stimulus. Alkaloids are a large group of nitrogenous substances found in naturally in plants, many of which have extracts that are pharmacologically active.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
