Physiology of Glucose and Insulin

Front

What is the primary energy source for cell metabolism?

Back

Glucose

Front

What hormone facilitates glucose transport into the cell?

Back

Insulin

Front

Where does endocrine regulation of glucose occur?

Back

In the islets of Langerhans cells in the pancreas.

Front

What do alpha cells secrete?

Back

Glucagon

Front

What do beta cells secrete?

Back

Insulin

Front

How does insulin enter liver circulation?

Back

Through basal (fasting) and prandial (post-food ingestion) secretion.

Front

What is the role of insulin in normal metabolism?

Back

To maintain homeostasis of blood glucose and lipid levels.

Front

What process does insulin inhibit in the liver?

Back

Glycogenolysis and very low-density lipoprotein production.

Front

What happens when insulin production is ineffective?

Back

Glucose is prevented from entering cells, blood glucose levels rise, and metabolism is impaired.

Front

What is the major source of glucose from foods?

Back

Monosaccharides from the breakdown of carbohydrates.
