Question

Despite being a small polypeptide, what is the regulatory potency of glucagon?

A) Low potency
B) Moderate potency
C) Very high potency
D) No potency

Answer 1

Glucagon is a small polypeptide hormone that has a very high regulatory potency. It stimulates mechanisms that increase blood glucose levels.

Step-by-step explanation:

Glucagon is a small polypeptide hormone that has a very high regulatory potency. It is secreted by the alpha cells of the islets of Langerhans in the pancreas in response to low blood glucose levels. Glucagon stimulates mechanisms that increase blood glucose levels, such as glycogenolysis, gluconeogenesis, and lipolysis.
