hard · MCQ · Q-24D64F
During prolonged fasting, which combination of hormonal changes and metabolic effects is expected?
- A.Increased insulin, decreased glucagon, and enhanced glycogen synthesis
- B.Decreased insulin, increased glucagon, and enhanced hepatic glycogenolysis and gluconeogenesisCorrect answer
- C.Increased insulin, increased glucagon, and reduced release of glucose by the liver
- D.Decreased insulin, decreased glucagon, and increased glucose uptake by all body cells
Solution
Fasting lowers blood glucose and therefore decreases insulin secretion while increasing glucagon secretion. Glucagon promotes hepatic glycogenolysis and gluconeogenesis to maintain blood glucose levels.
