Question

Quizplus · Accepted Answer

Protein hormones are secreted in response to a specific stimulus, such as a change in blood glucose levels or the presence of a hormone-releasing hormone. This process is called stimulus-secretion coupling, and it ensures that hormones are released into the bloodstream only when they are needed. Constitutive secretion, on the other hand, is the continuous release of proteins from cells without regulation. Endocytosis recycling, signal peptidase-induced cleavage, and membrane shedding are not mechanisms involved in the regulation of protein hormone secretion.
