6.2.2.1. Formation of glucose 6-phosphate Glycogen

i). Glycogenesis

Glycogenesis is the process of biosynthesis of glycogen from glucose and occurs mainly in muscle and liver. The following steps are involved

Formation of glucose 6-phosphate

Glucose is phosphorylated to glucose 6-phosphate, a reaction that is common to the first reaction in the pathway of glycolysis from glucose. This reaction is catalyzed by hexokinase in muscle and glucokinase in liver.

Hexokinase

Glucose + ATP → Glucose 6-phosphate + ADP
