Question

Q12. Describe what the liver does when presented with a glucose load.   

In your answer include the relevant biochemical pathways.

Answer 1

ANSWER :

When the serum glucose levels in the blood elevated to its normal range, then excess glucose converted into the glycogen during the process of glycogenesis via the enzymatic activity of insulin hormone, which secretes from the beta cells of pancreas, and temporarily stored in the liver.

But during the prolonged period of fasting, or vigorous physical exercise, when the blood glucose levels signifucai decreased down, the stored glycogen reconverted into the glucose during the glycogenolysis process via the enzymatic activity of glucagon hormone (secreted from the alpha cells of pancreas), and released into the blood to maintain the glucose levels back to its normal range.
