| Increased rate | Decreased rate | No change |
| Treatment with glucagon | Treatment with insulin | |
| Treatment with epinephrine | Addition of kinase inhibitor | |
| Addition of phosphatase inhibitor | Removal of phosphate group from phosphorylase a | |
| [ATP] exceeds [AMP] | AMP allosteric binding actiavtes phosphorylase b |
Glycogenolysis is breakdown of glycogen molecule. This process is activated by phosphorylase a (phosphorylated), Glucagon, epinephrine.
phosphorylation of phosphorylase by kinase increases glycogenolysis. Removel of phospahte by phosphotases decreases it.

In muscle tissue, the ratio of phosphorylase a to phosphorylase b determines the rate of conversion of glycogen to glucose 1-phosphate. Classify how each event affects the rate of glycogen breakdown in isolated muscle tissue. Increased rate ; Decreased rate ; No change Option: addition of phosphorylase b kinase ; addition of a phosphatase inhibitor ; end of fight-or-flight response ; treatment with glucagon ; AMP allosteric binding activates phosphorylase b ; treatment with insulin ; addition of phosphatase PP1...

In muscle tissue, the ratio of phosphorylase a to phosphorylase b determines the rate of conversion of glycogen to glucose 1‑phosphate. Classify how each event affects the rate of glycogen breakdown in isolated muscle tissue. The classifications are Increased rate, Decreased rate, No change. Answer Bank: AMP allosteric binding activities phosphorylase b, addition of a phosphate inhibitor, addition of phosphorylase b kinase, removal of phosphate groups from phosphorylase a, end of fight-or-flight response, ATP exceeds AMP, treatment with insulin, treatment...

I had this partially wrong too
The muscle and liver forms of glycogen phosphorylase respond to different allosteric effectors consistent with the energy status of a given tissue. Select the correct type of regulation with the correct isozyme. AMP ATP Activates liver phosphorylase a Activates liver phosphorylase b Glucose Inhibits liver phosphorylase a Inhibits liver phosphorylase b Glucose 6-phosphate Activates muscle phosphorylase a Activates muscle phosphorylase b Inhibits muscle phosphorylase a | Inhibits muscle phosphorylase b
