How glutamine be utilized for energy
Web3 jan. 2012 · One route of glutamine catabolism involves its conversion to glutamate by glutaminase (GLS) in mitochondria. Glutamate is, in turn, deaminated to generate α-ketoglutarate (α-KG). α-KG can then... WebGlutamine is formed by a reversible reaction involving the coupling between the exergonic cleavage of adenosine triphosphate (ATP) to adenosine diphosphate and inorganic phosphate and the endergonic addition of ammonia to glutamate. The carbon of α-ketoglutarate destined to become glutamine can come from glucose [ 18.
