Answer: glucose from amino acids.
Step-by-step explanation:
It is a process that occurs only in the liver, where the body synthesizes glucose from non-glycolytic molecules, for use mainly by the glycosidic organs brain, and myocardium. This process occurs when there is a need for energy and the lack of intracellular glucose. Occurs when the body is in a state of prolonged hunger or cell starvation as in pathology diabetes.
Irreversible reactions of the Gluconeogenesis pathway and the glycolytic pathway are located in the same positions. This serves as a mechanism by which the Gluconeogenesis only occurs when necessary and when it is not inhibited by the glycolytic pathway. The glycolytic pathway is negatively controlled in those points at the time the Gluconeogenesis is occurring. If Gluconeogenesis occurred at the same time as the glycolytic path, both routes would be canceled.
