WebThe glycogen phosphorylase or also termed s phosphorylase is mainly regulates the rate of glycogenolysis in liver and muscles. Phosphorylase exists in active state as (phosphorylase a) and inactive state as (phosphorylase b). There are two separate pool of phsophorylases in muscles as well in liver cells. WebGlycogen phosphorylase causes phosphoroclastic cleavage into glycogen, and produces glycogen-1-phosphate. However, a non-reducing terminal is removed when cleaving glucose from glycogen. Moreover, if glucose-1-phosphate produced from glycogen is changed into G6P by phosphoglucomutase, it can proceed directly to glycolysis.
