Please answer only if you are confident. These are all my wrong attempts. Please just list the answers without hiding them in explanation.

muscle tissue, the ratio of phosphorylase a to phosphorylase b determines the rate of conversion of giycogen to glucose 1-phosphate Classify how each event affects the rate of glycogen breakdown in isolated muscle tissue. Increased rate Decreased rate No change addition of phosphorylase b kinase addition of phosphatase PP1 AMP allosteric binding activates phosphorylase b addition of a kinase inhibitor addition of a phosphatase inhibitor treatment with insulin [ATP] exceeds [AMP] Incorrect. Although other events may be misplaced, you have not accurately classified how small molecule modulators affect the rate of glycogen breakdown. The enzyme that controls glycogen breakdown, glycogen phosphorylase, is affected by allosteric binding of AMP and Ca2t. Classify each event based on whether or not allosteric regulation occurs.

Explanation / Answer

Increased rate

addition of phosphorylase b

AMP activates phosphorylase b

addition of phosphatase inhinitor

Decreased rate

addition of PP1

addition of kinase inhibitor

ATP exceeds AMP

No change

treatment with insulin (insulin affects only the liver)
