Which of the following would cause liver cells to break down their glycogen stores, and release glucose to the blood; and, when would this occur? a) high insulin and low glucagon; immediately after a meal b)low insulin and high glucagon; several hours after a meal c)high insulin and high glucagon; several hours after a meal d)low cortisol and low glucagon; immediately after a meal
Homework Answers
(b)low insulin and high glucagon;immediately after a meal.
The glycogen storage in the body breaks down when there is low glucose level in the blood and the production of insulin is low.It triggers more secretion of a hormone glucagon which breaks down the glycogen in liver into glucose to fulfill the need of glucose in blood.

B. Insulin is secreted in response to low levels of blood glucose. C. Glucagon and epinephrine have opposing effects on glycogen metabolism. D.

2. Individuals lacking liver glucose-6-phosphatase accumulate a large amount of glycogen in the liver, while their blood glucose levels are only slightly increased when administered high doses of glucagon. What is the metabolic source of the glucose that causes the blood glucose levels to rise slightly? Justify your answer with key metabolic information regarding how glucagon affects cells, how the mutation changes cellular function, and how the glucose exits the cell.
