WebEmbed Script. Size (px) WebGlycogen phosphorylase is the primary enzyme in the breakdown of glycogen and glycogen synthase is the rate-limiting enzyme in glycogen synthesis. The regulation of these two …
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. WebPhosphorylase Glycogen phosphorylase is a lytic enzyme in glycogenolysis. Phos-phorylase joins a phosphate group to the glucose residue of glycogen and catalyzes the phosphorylation reaction and consequently the cleav-age of glucose from glycogen in the form of G1P (phosphorolysis reaction). Phosphorylase is in either the active (R) form or …
