Concept explainers
Interpretation: Explain how the hormones insulin and glucagon regulate the rates of glycogenesis, glycogenolysis and glycolysis.
Concept Introduction: Glycogenesis is the reverse process of glycogenolysis. In glycogenesis, glycogen is synthesized from glucose. Glycogenolysis process is regulated by the hormonal activity, when the level of glucose is less in the body.
Glycogenolysis is the process of breakdown of glucose of n-residues into glucose-1-phosphate and glucose of (n-1) residues in the presence of several enzymes, such as glycogen phosphorylase, phosphoglucomutase. The glycogenolysis process is regulated by the hormonal activity when the level of glucose is less in the body.
Glycolysis is the process of breaking down of 6-carbon molecule, glucose into two molecules of 3-carbon molecule, pyruvate. Alarge amount of energy is released in the glycolysis process. Glycolysis is a pathway of several
Gluconeogenesis is the process of synthesis of glucose from non-carbohydrate carbon compounds, such as glycerol, lactate. The Gluconeogenesis process is regulated by the hormonal activity when the level of glucose is less in the body.
