WebEither alpha or beta-adrenergic receptors will receive and be activated by the norepinephrine. The difference in receptor type alpha or beta will determine the response which can include vasodilation or vasoconstriction. This opposing response to the same neurotransmitter is key to the fight or flight reaction, as we will see next. WebFluorescence studies with purified human beta(2)-adrenoceptor (beta(2)AR) revealed that the endogenous catecholamines, (-)-epinephrine (EPI), (-)-norepinephrine (NE), and …
