During the Absorptive State of Metabolism

Question

During the absorptive state of metabolism
A)liver glycogen is broken down to glucose,which is released into the blood.
B)glycogen in muscle cells is broken down to glucose,which is used for energy.
C)lipoprotein lipase breaks down triacylglycerols in adipose tissue capillaries.
D)fatty acids and glycerol are released from adipose tissue.
E)lactate and pyruvate secretion into the bloodstream by the muscles increases.

Accepted Answer

During the absorptive state of metabolism, lipoprotein lipase breaks down triacylglycerols in adipose tissue capillaries. This releases fatty acids and glycerol for use as energy or storage in adipocytes. The liver also takes up glucose from the bloodstream and stores it as glycogen, while muscle cells may take up glucose from the bloodstream for immediate use or storage as glycogen. Lactate and pyruvate secretion may increase during intense exercise, but this is not necessarily a characteristic of the absorptive state.
