B) High lipid levels
C) Diabetes
D) Respiratory disease
D
Feedback:
Beta2-receptors are found in the smooth muscle in blood vessels, in the bronchi, in the periphery, and in uterine muscle. Beta2-receptors also cause dilation in the bronchi. Beta1-receptor stimulation would improve some heart disease and are responsible for increased lipolysis. Because beta2-receptors increase release of glucagon and the breakdown of glycogen, increasing serum glucose levels, stimulation of these receptors would exacerbate diabetes.
