The following diagram shows a feedback mechanism involved in the regulation of blood glucose levels.
A diagram shows the cycling of blood sugar, glucagon, and glucose between the liver and pancreas. An arrow comes from a box labeled low blood sugar and points to the pancreas. This arrow is labeled promotes glucagon release. From the pancreas, an arrow points to a box labeled glucagon and from the box, the arrow continues to the liver. A label on the part of the arrow between glucagon and the liver says stimulates glycogen breakdown. Inside the liver, labels and arrows indicate that glycogen converts to glucose. An arrow comes out of the other side of the liver and points to a label that says raises blood sugar.
Which of the following predict a likely effect on an individual if the liver fails to convert glycogen to glucose?
