Some of the amino acids are convertible (with the expenditure of energy) to glucose and can be used for energy production just as ordinary glucose.

The cells will use glucose for energy as normal, and any glucose not used for energy will enter the polyol pathway and be converted into sorbitol.

Any excess glucose stimulated the pancreas to release insulin, which transported glucose into peripheral fat tissue, and which also caused the liver to store glucose as glycogen (liver starch).

While the oxygen concentration is low, the product of glycolysis, (pyruvate), is turned into ethanol and carbon dioxide, and the energy production efficiency is low (2 moles of ATP per mole of glucose).

And of course, the desired range trying to keep glucose between 75 and less than 200, checking it every five minutes in a continuous glucose sensor you'll see how that can impact diabetes.
