Which of the choices below is NOT a source of blood glucose during the postabsorptive state? Question 6 options: 1) glycogenolysis in the liver 2) lipolysis in adipose tissues and the liver 3) absorption of glucose from the GI tract 4) catabolism of cellular protein

3) option is correct

Explanation:

Post absorptive state energy metabolism is mostly catabolic which means there is breakdown of macromolecules to release glucoseFatty acids are the primary energy source (except in brain)Post absorptive state is largely caused by lack of insulin and also utilizes glucagon, but stress hormones (cortisol and epinephrine) can fill in for glucagonGlucagon mainly affects liver So, absorption of glucose from the GI tract is not a source of blood glucose during the post absorptive state
