Occurs in starvation rather than well fed state, C. Always activated by c-AMP dependent protein kinase, D. Always activates the enzyme', 'role': 'user'}, {'content': "Answer: C \nExplanation: Ans. c. Always activated by c-AMP dependent protein kinaseEpinephrine and norepinephrine (in muscle during activity) or glucagon (in liver when blood glucose level is too low) increase concentration of c-AMP, which inturn activates c-AMP dependent protein kinase (protein kinase a or PICA).Allosteric Control of Phosphorylase occurs throughIn MuscleActivation: Ca2+degc-AMPdeg5'-AMP Inhibition: - ATPdegGlucose-6-phosphateIn LiverActivation: - c-AMPdegInhibition:ATPdegGlucose-6-phosphate Free glucosedeg", 'role': 'assistant'}]
