WebJan 27, 2024 · Norepinephrine (also called noradrenaline) is used as a neurotransmitter and influences sleep and wakefulness, arousal, attention, and feeding behavior. Perhaps the most prominent noradrenergic neurons are sympathetic ganglion cells, which employ norepinephrine as the major peripheral transmitter in this division of the visceral motor … WebIn the adrenal medulla, norepinephrine is converted to epinephrine in a methylation step catalyzed by phenylethanol-N-methyl transferase; S-adenosylmethionine (SAM) is the methyl donor. This reaction takes place in the cytoplasm, but the epinephrine reenters the granule after its methylation.
