What happens to glucose in diabetic animals suffering from cellular starvation despite hyperglycemia?
What happens to glucose in diabetic animals suffering from cellular starvation despite hyperglycemia?
- Glucose is converted into ketones for energy production (correct)
- Glucose is excreted through urine
- Glucose moves into cells for energy production
- Glucose is stored in the liver for later use
What is the purpose of ketone production in diabetic animals during hypoglycemia?
What is the purpose of ketone production in diabetic animals during hypoglycemia?
- To reduce glucose levels in the blood
- To increase insulin resistance
- To promote glucose uptake by cells
- To provide a substrate for energy metabolism (correct)

Study Notes
Diabetes Mellitus
- Type 1 diabetes mellitus is characterized by an absolute insulin deficiency.
Cellular Starvation and Hyperglycemia
- Despite hyperglycemia, glucose is not utilized by cells in diabetic animals, leading to cellular starvation.
Ketone Production
- Ketone production in diabetic animals serves as an alternative energy source during hypoglycemia.
Insulin Resistance and Ketone Production
- The main factor that leads to increased insulin resistance and ketone production in diabetic ketoacidosis is the combination of insulin deficiency and counter-regulatory hormone excess.
Diabetic Ketoacidosis
- Diabetic ketoacidosis is considered an emergency because it can lead to severe complications, including dehydration, acidosis, and even death if left untreated.
