Question

which is a function of glucagon?
o a. the breakdown of glycogen from the liver
o b. the uptake of glucose from the blood into cells
o c. the storage of glycogen in the liver and muscles
o d. the conversion of excess glucose into fat for storage

Explanation:

Glucagon is a hormone that raises blood glucose levels. When blood glucose is low, glucagon is released. It acts on the liver to break down glycogen (stored glucose) into glucose, which is then released into the bloodstream.

• Option b is the function of insulin (which lowers blood glucose by promoting glucose uptake into cells).
• Option c is related to insulin's role in promoting glycogen storage (when glucose levels are high).
• Option d is also an action associated with insulin (converting excess glucose to fat for storage).

Answer:

A. The breakdown of glycogen from the liver
