Question 13

2 / 2 pts

Neuroglycopenic symptoms (dizziness, obtunded or altered mental status) become evident when hypoglycemia occurs (glucose levels < 50). To elevate plasma glucose levels back to normal range (60 to 100), glucagon hormone, released from alpha cells of the pancreas, increases blood glucose levels by directing liver cells to start glycogenosis (breaking down of glycogen, a polysaccharide polymer made up of glucose units) into glucose (a monomer) which is then in turn transferred to the blood.

True

False

Glucagon also stimulates gluconeogenesis, the process of synthesizing glucose from non-carbohydrate sources, further aiding in the restoration of normal blood glucose levels.
