During the absorptive state, insulin levels are low. The liver forms glycogen, while skeletal muscle breaks down glycogen. Adipocytes release fatty acids into the circulation, and skeletal muscle fibers release glucose.

Muscle cells store enough ATP and phosphocreatine for about ________ of exercise. 15 seconds 5 minutes 15 minutes 35 seconds Insulin concentration decreases during exercise. What is the advantage of this phenomenon? Glucose is more available to contracting muscle cells. It keeps the plasma osmolarity low. Glucose levels are low during exercise. There is no reason for insulin to circulate. Insulin release is inhibited by the appearance of glycerol in the bloodstream from lipolysis of adipose tissue.

Click and drag the terms to indicate how insulin levels affect human metabolism: A high level of insulin will decrease gluconeogenesis. A low level of insulin will increase the catabolism of amino acids in energy-yielding pathways. A high level of insulin will increase lipolysis. A low level of insulin will decrease the synthesis of glycogen. A high level of insulin will increase glycolysis.
