Hyperglycemia occurs when:

Hyperglycemia occurs when:

• A. Blood glucose levels rise, stimulating the production of insulin.
• B. The body responds to glucose-starved tissues by changing stored glycogen into glucose.
• C. Insulin conversion of glycogen to glucose is inhibited.
• D. Glycogen is unable to be stored in the liver and muscles.

Answer: (B)

The main concept is that hyperglycemia can result from glycogenolysis in the liver, where stored glycogen is converted into glucose to be released into the bloodstream. When tissues are glucose-starved, hormonal signals stimulate the liver to break down glycogen into glucose, raising blood glucose levels to supply essential organs like the brain. This is why the statement that describes converting stored glycogen into glucose best fits hyperglycemia: it captures the process by which glucose is released into the blood. The other ideas either describe a response that would lower blood glucose (insulin secretion in response to high glucose), misstate how insulin works (insulin promotes storage of glucose as glycogen rather than conversion of glycogen to glucose), or refer to glycogen storage issues that don’t directly explain the rise in blood glucose.
