Document Summary
Makes g6p -> pyruvate -> citric acid cycle -> atp. Glycogen - quick and easy to get sugar out. Liver exports all its glycogen storage to maintain blood sugar levels. Glucose produced from amino acids via gluconeogenesis. Takes about 3 days for fatty acids metabolism to become the main energy source. Muscles will break down excess proteins to give to the liver for gluconeogenesis. However, not a good idea to use this for a long time. An average person can live about 2-3 months on their triacylglycerols storages. If you continue to starve after you will go back to breaking down muscles. Take amino acids and fed them into gluconeogenesis. Where liver gets most of its energy. Liver does not use any of its own glucose storages for energy. Use whatever energy sources it can get take glucose out of the bloodstream. Will break down glycogen for its own use in glycolysis.
