Noradrenergic receptors

Question

Quizplus · Accepted Answer

Noradrenergic receptors are metabotropic, meaning they act through G proteins to activate signal transduction pathways inside the cell. They can stimulate or inhibit different enzymes, including adenylyl cyclase, which is responsible for producing the second messenger cAMP. However, the specific effect on adenylyl cyclase depends on the subtype of noradrenergic receptor and the tissue or cell type where it is expressed. Some subtypes, such as alpha-2 receptors, inhibit adenylyl cyclase, while others, such as beta receptors, stimulate it.
