Define gluconeogenesis. What organs can it occur in? What precursors can be used? What is the outcome?
Gluconeogenesis is the synthesis of glucose from a noncarbohydrate precursor. It occurs because cells cannot use acetyl-CoA to make glucose. Gluconeogenesis can take place in the liver and in skeletal muscles. Lactate, glycerol and some amino acids can be precursors for gluconeogenesis but fatty acids and other amino acids that produce acetyl-CoA cannot. The end result is an increase in the production of glucose that can be used or stored as glycogen.
