WebGlycogen phosphorylase is the main regulatory step Glycogenolysis speeds up (activation) High energy need AMP, epinephrine low blood glucose levels Glucagon Glucagon etymology Gluc = ‘glucose’ and agon = agonist Glucagon means ‘glucose agonist’ so it increases blood glucose levels Glycogenolysis slows down (inhibition) low energy need ATP WebApr 16, 2024 · The distinction is that hydrolysis reactions use water to cleave bigger molecules into smaller ones, but phosphorolysis reactions use phosphate instead for the same purpose. Note that the phosphate is just that - it does NOT come from ATP. Since ATP is not used to put phosphate on G1P, the reaction saves the cell energy.

WebThe rate-limting enzyme is glycogen phosphorylase. While a hydrolase uses water to break bonds, a phosphorylase uses an inorganic phosphate. Glycogen phosphorylase is activated by glucagon in the liver, but AMP and epinephrine in the liver. It is inhibited by ATP. Glycogen phosphorylase can only break α-1,4 bonds.
