Question

Which of the following statements is true of the absorptive state (compared to the postabsorptive state)?

		Lipids are broken down in adipose tissue.
		Most body cells use fatty acids for energy, sparing glucose for the nervous system.
		Insulin levels are low and glucagon levels are high.
		Glycogenolysis is increased.
		Gluconeogenesis is inhibited.

Answer 1

D) Glycogenolysis is increased.

Explanation : absorptive state is a highly active energy dependent process It continuously requires energy in the form of ATP so as to transport the molecules from lumen through the absorptive surface. The energy for the the absorption and transport comes from the breakdown of glucose which provides ATP. So there will be increased glucose uptake by the cell. Hence for this requirement, glycogen has to be broken down to produce free glucose by a process called Glycogenolysis. So Glycogenolysis is increased in absorptive state.

Lipids are stored within the adipose tissue.

Most body uses glucose for energy.

Gluconeogenesis is increased in absorptive state and insulin level is also increased to allow entry of glucose into the cell
