Ksivusya [100]
<h2>cAMP and glucose mobilization</h2>

Explanation:

It would maintain high cAMP level and elevate glucose mobilization

  • Phosphodiesterase is an effector enzyme which degrades secondary messenger cAMP(cyclic adenosine monophosphate)
  • Here in this case an inhibitor is inhibiting the phosphodiesterase therefore cAMP level will increase
  • As cAMP level rise it activates a protein called protein kinase A which phosphorylates phosphorylase kinase and activates it
  • Phosphorylase kinase becomes active that phosphorylates glycogen phosphorylase and makes it active,glycogen phosphorylase catalyse breakdown of glycogen(in liver and muscle cells)
  • In liver cells breakdown of glycogen occurs and glucose 1 phosphate gets converted into glucose and supplied to whole body through blood
