WebMay 8, 2024 · Glycogenesis or glycogen synthesis is a multi-step process that begins with converting glucose to glucose-6-phosphate via hexokinase or the liver isoform of hexokinase known as glucokinase. This process is an essential step as the addition of a phosphate group traps glucose within the cell. G6P subsequently converts to glucose-1 … WebGlycogen synthesis (called glycogenesis) commences from glucose 6-phosphate (Figure 11.7) which may be produced from glucose absorbed from the bloodstream as in skeletal muscle or by gluconeogenesis (Section 11.6) from C 3 compounds, e.g. lactate, as in liver.
