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 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 [ATP] exceeds [AMP]

Step 1
Addition of phosphorylase b kinase: This enzyme converts phosphorylase b to phosphorylase a, increasing the ratio of phosphorylase a to phosphorylase b, and thus increasing the rate of glycogen breakdown. So, the effect is an **increased rate**. Show more…
