Question

If your liver starts breaking down glycogen into glucose molecules, what is likely taking place elsewhere in the body?

a. A excess of sugar in the blood is causing the pancreas to release the hormone glucagon.

b. A shortage of sugar in the blood is causing the pancreas to release the hormone glucagon.

c. An excess of sugar has caused the release of insulin.

d. There is not enough sugar in the blood stream, which stimulates the kidneys to release more glucose.

Answer 1

The answer should be B. Glycogen is a storage form of carbohydrates in human body, and its converted from glucose. Only if we don't have enough sugar in our blood will make the glucose level raise. To raise the level, a hormone called glucagon will convert stored glycogen back into glucose and release into blood.
However, insulin is the opposite of glucagon. It lowers the glucose level instead.

Answer 2

B. A shortage of sugar in the blood is causing the pancreas to release the hormone glucagon.
