GENERAL KNOWLEDGE

Detailed explanation-1: -After a meal, glucose enters the liver and levels of blood glucose rise. This excess glucose is dealt with by glycogenesis in which the liver converts glucose into glycogen for storage. The glucose that is not stored is used to produce energy by a process called glycolysis. This occurs in every cell in the body.

Detailed explanation-2: -In the fed state, glucose enters hepatocytes via GLUT2 and is phosphorylated by glucokinase and used to synthesize glycogen by glycogen synthase (4). In the fasted state, glycogen is hydrolyzed by glycogen phosphorylase to generate glucose (glycogenolysis) (Fig.

Detailed explanation-3: -When the body doesn’t need to use the glucose for energy, it stores it in the liver and muscles. This stored form of glucose is made up of many connected glucose molecules and is called glycogen.

Detailed explanation-4: -The liver supplies sugar or glucose by turning glycogen into glucose in a process called glycogenolysis. The liver also can manufacture necessary sugar or glucose by harvesting amino acids, waste products and fat byproducts. This process is called gluconeogenesis.
