has primary input (R)-noradrenaline(1+) cellular response to chemical stimulus cellular response to catecholamine stimulus response to norepinephrine cellular response to norepinephrine stimulus mah GO:0071874 cellular response to noradrenaline stimulus Note that epinephrine and norepinephrine are ligands for the same receptors, and there are multiple adrenergic receptors. 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 norepinephrine stimulus. Norepinephrine is a catecholamine that has the formula C8H11NO3; it acts as a hormone, and as a neurotransmitter in most of the sympathetic nervous system. 2010-09-13T03:33:32Z
