WebIn contrast, phosphorylase a is fully active, regardless of the levels of AMP, ATP, and glucose 6-phosphate. What does phosphorylase b do? Hepatic glycogenolysis releases glucose to the bloodstream when blood glucose is low, which then is carried to all body tissues. Phosphorylase kinase b is also allosterically activated by high levels of Ca 2 +. Web2 jul. 1973 · Only few cases of true liver phosphorylase deficiency have been reported (5,6,7).
