In the postabsorptive state, where do the body's tissues get most of their glucose?

Question

Quizplus · Accepted Answer

In the postabsorptive state (fasting state), the liver undergoes gluconeogenesis to produce glucose for the rest of the body. Since liver glycogen stores are depleted quickly, the liver then turns to amino acids from muscle protein to produce glucose. However, this process is not the primary source of glucose for the body's tissues. Therefore, the correct answer is C, where liver glycogen provides the majority of glucose for the body's tissues in the postabsorptive state. Muscle glycogen can also contribute to glucose production, but it is primarily used by the muscle itself for energy during exercise. Adipose stores do not produce glucose but can be broken down into fatty acids and glycerol to provide energy for the body.
