Phosphorylation vs hydrolysis
WebIn phosphorolysis, glycogen phosphorylase uses Pi (inorganic phosphate) to make G-1-Phosphate, without the need for ATP. Hydrolysis requires ATP. The concentration of inorganic phosphate inside the cell is high enough to drive the reaction forward. Describe the significance of glycogenolysis in liver versus muscle. Webphosphorolysis: [noun] a reversible reaction analogous to hydrolysis in which phosphoric acid functions in a manner similar to that of water with the formation of a phosphate …
