GO:0007186 | G protein-coupled receptor signaling pathway | biological_process | The series of molecular signals initiated by a ligand binding to its receptor, in which the activated receptor promotes the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, and ends with regulation of a downstream cellular process. The pathway can start from the plasma membrane, Golgi or nuclear membrane.

GO:0019226 | transmission of nerve impulse | biological_process | The neurological system process in which a signal is transmitted through the nervous system by a combination of action potential propagation and synaptic transmission. [GOC:curators, ISBN:0815316194] |
GO:0050913 | sensory perception of bitter taste | biological_process | The series of events required to receive a bitter taste stimulus, convert it to a molecular signal, and recognize and characterize the signal. This is a neurological process. [GOC:ai] |
GO:0050916 | sensory perception of sweet taste | biological_process | The series of events required to receive a sweet taste stimulus, convert it to a molecular signal, and recognize and characterize the signal. This is a neurological process. [GOC:ai] |
GO:0050917 | sensory perception of umami taste | biological_process | The series of events required to receive an umami taste stimulus, convert it to a molecular signal, and recognize and characterize the signal. Umami taste is the savory taste of meats and other foods that are rich in glutamates. This is a neurological process. [GOC:ai] |
GO:0005886 | plasma membrane | cellular_component | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363] |
