Answer to Question 1
The glycogen stored in the liver provides a reserve supply of the body's sugar, glucose, and thus can sustain cell activities if intervals between meals become so long that glucose absorbed from ingested foods is used up. When the body is depending solely on liver glycogen, however, the supply is used up within three to six hours. Similarly, fat cells store reserves of fat, the body's other principal energy nutrient. Unlike the liver, however, fat cells have virtually infinite storage capacity and can continue to supply fat for days, weeks, or even months when no food is eaten.
