how does an increase in the cellular ion concentration influence glycogen phosphorylase activity?
Homework Answers
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.
