WebThe hormone epinephrine binds to β adrenergic receptors on smooth muscle cells of the bronchioles, causing them to dilate (increase in diameter). Thyroid hormone is essential for the synthesis of β adrenergic receptors; therefore, in the absence of thyroid hormone, epinephrine cannot trigger bronchodilation. This concept is known as __________. WebIn the first step of the signal transduction pathway involving cAMP, a signal molecule binds to and activates a receptor called ___. This causes a G protein to bind ___, which promotes the dissociation of the α subunit from the β/γ dimer. ... Other Quizlet sets.
