Question

Quizplus · Accepted Answer

Stimulation of beta-adrenergic receptors can lead to an increase in metabolic activity (1) and the breakdown of triglycerides within adipocytes (3). However, it does not lead to contraction of airway smooth muscle (2); this is the effect of stimulation of beta-2 adrenergic receptors. Therefore, only statements 1 and 3 are true in this case.
