Norepinephrine binds to adrenergic receptors
Did you know?
WebAt the molecular level, it binds to the receptor and blocks the binding of epinephrine and norepinephrine, resulting in a decrease in heart rate, contractility, and conduction velocity. It also has non-selective beta-blocking effects on beta-2 receptors, resulting in bronchodilation and vasodilation.

WebSubtypes of both alpha- and beta-adrenoceptors exist. In the periphery, alpha 1-receptors are located postsynaptically, mediating the excitatory effects of catecholamines at alpha-receptors. alpha 2-Adrenoceptors, on the other hand, are autoreceptors involved in the regulation of noradrenaline (norepinephrine) release.
