Adrenergic receptor

The adrenergic receptors (or adrenoceptors) are a class of G-protein coupled receptors that is the target of catecholamines. Adrenergic receptors specifically bind their endogenous ligands, the catecholamines adrenaline and noradrenaline (also called epinephrine and norepinephrine) and are activated by these.

Many cells possess these receptors, and the binding of an agonist will generally cause the cell to respond in a flight-fight manner. For instance, the heart will start beating quicker and the pupils will dilate.
