After eating, the body immediately starts to break the glucose down into energy. 24 Full PDFs related to this … Glycogenesis takes place when blood glucose levels are sufficiently high to allow excess glucose to be stored in liver and muscle cells. Conclusion Glycogenolysis and gluconeogenesis are two processes involved in the formation of glucose inside the body in response to low glucose levels. And it does turn out that ATP is actually an allosteric regulator of a couple enzymes in glycolysis. These compounds include lactate and pyruvate; the compounds of the tricarboxylic acid cycle, the terminal stage in the oxidation of foodstuffs; and several amino acids. Thus Gluconeogenesis is a biochemical term that describes the synthesis of glucose or glycogen from substances which are not carbohydrates. References Lehninger Principle of Biochemistry by David L.
