Document Summary

Glycogen phosphorylase p is used to clear the x 1,4 glycosidic linkage through phosphorolysis and yields glucose. 1 6 bisphosphatase an enzyme called glucose 1. 6 bisphosphatase synthase that makes glucose 1 6 bisphosphate from 1,3 bisphospho glycerate. Or e forms lactate waste product due to lack of oxygen and a mitochondria. 1,6 requires a separate enzymatic system a distinct enzyme is needed to deal with branched nature of glycogen debranching enzymes functions to catalyze a reaction two step a 4 l d glucanotransferase function. First step is the productionof glucose 6 phosphate phosphoglucomutase concerts glucose g phosphate into glucose l phosphate glucose l phosphate uridylytransferase uses glucose l phosphate and utp to form udp glucose and pp. The two targets for regulations are and glycogen synthase the glycogen phosphorylase both are targets for allosteric regulation effectors and covalent modifications. 1 glycogen phosphorylase effectors allosteric regulation are amp glucose and atp a amp increase glycogen phosphorylate because you need.
