Glycogen phosphorylase is not inactive in muscles. It is activated when there is increase in AMP concentration. In the case of strenuous exercise when there is a need for glycogen breakdown, hormones like epinephrine is released. This activated the breakdown of ATP into AMP which activates the inactive glycogen phosphorylase b into active glycogen phosphorylase. This leads to the breakdown of glycogen into glucose. When there is no need for the breakdown ( in the abundance of ATP Concentration) the glycogen phosphorylase remains inactive.
how does an increase in the cellular ion concentration influence glycogen phosphorylase activity?
Q5. The phosphorylase enzyme, which is involved in breakdown of glycogen to glucose, is controlled by both allosteric mechanisms and posttranslational modification. A) Describe how the T to R transition and activity of glycogen phosphorylase would change under the following conditions: i) high AMP levels and activation of phosphoprotein phosphatase, ii) activation of phosphorylase kinase, ili) activation of phosphorylase kinase and high glucose levels. B) What properties would an uncompetitive inhibitor of glycogen phosphorylase have, what would the Lineweaver Burk...
