Binding of Epinephrine to Adrenergic Receptors Induces Tissue-Specific Responses. Epinephrine and norepinephrine were originally recognized as products of the medulla, or core, of the adrenal gland and are also known as adrenaline and noradrenaline.
bind to membrane receptors, are often used in paracrine and autocrine signaling. They generally modulate the effect of other hormones. Once a signaling molecule binds to its receptor it causes a conformational change in it that results in a cellular response. The same ligand can bind to different receptors causing different responses (e.g.. acetylcholine). On the other hand, different ligands binding to different receptors can produce the. same cellular response (e.g. glucagon, epinephrine).
