Phosphorolysis via glycogen phosphorylase
WebPhosphorolysis is the cleavage of a compound in which inorganic phosphate is the attacking group. It is analogous to hydrolysis. [1] An example of this is glycogen breakdown by glycogen phosphorylase, … WebPhosphorylase is one of the enzymes of glycogenolysis that directly generates In the fasting state, the hormone glucagon the enzyme, resulting in in blood glucose levels. Show transcribed image text Expert Answer 100% (107 ratings) ANSWER: Glycogen phosphorylase catalyzes a phosphorolysis reaction that breaks α-1,4-linkages in glycogen.

WebGlycogen phosphorylase (GP) is an important therapeutic target for type 2 diabetes having a direct influence on blood glucose levels through the glycogenolysis pathway. GP is an … WebGlycogen phosphorylase causes phosphorylation of glycogen that results in the formation of glucose-1-phosphate by the breakdown of glycogen. Phosphoglucomutase can then proceed to convert glucose-1-phosphate into glucose-6-phosphate. Glucose-6-phosphate can then either be fed into glycolysis, the pentose phosphate pathway or converted to …
