Why is GTP, not ATP, produced in Gluconeogenesis & TCA Cycle?

WebGluconeogenesis: Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources. The starting point of gluconeogenesis is pyruvic acid, although oxaloacetic acid and dihydroxyacetone phosphate also provide entry points. Lactic acid, some amino acids from protein and glycerol from fat can be converted into glucose. WebThe gluconeogenesis pathway consumes ATP, which is derived primarily from the oxidation of fatty acids. The pathway uses several enzymes of the glycolysis with the exception of enzymes of the irreversible steps namely pyruvate kinase, 6 … chinese brass vaseWeb4.1.1.49 - ATP Thus, there is no strict protocol for using specific energy carrier in the process, both ATP and GTP can be used in the reaction. Its just because GTP is more frequently used that it is mentioned instead of GTP/ATP in the reaction.
