Given below are two statements one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : Catecholamines stimulate the breakdown of glycogen resulting in an increased concentration of glucose in blood.
Reason (R) : Glucagon acts mainly on the liver cells (hepatocytes) and stimulates glycogenolysis resulting in an increased blood sugar. In the light of above statements, choose the most appropriate answer from the options given below:
Assertion is true. Catecholamines (adrenaline, noradrenaline) stimulate glycogen breakdown → increase blood glucose.
Reason is also true. Glucagon acts on liver and causes glycogenolysis.
But Reason talks about glucagon, not catecholamines, so it does not explain the Assertion.
