Glycogenolysis process steps

WebMar 7, 2024 · The steps of glycogenesis are as follows: Glucose phosphorylation – In the initial phase, glucose is phosphorylated into glucose-6-phosphate, a usual reaction in glycolysis. It is catalyzed by glucokinase (liver) and hexokinase (muscle). WebGlycogenolysis is not simply the reverse process of glycogenesis. The existence of irreversible reactions in glycogenesis requires glycogen degradation to be performed using different enzymes that can catalyze the unidirectional steps of the pathway. The stages of glycogenolysis are: 1.
