Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Glucagon is considered a hyperglycemic hormone. Reason (R): Glucagon acts mainly on hepatocytes to stimulate glycogenolysis and gluconeogenesis, while reducing cellular glucose uptake and utilisation. In the light of the above statements, choose the most appropriate answer from the options given be

Step-by-step solution

Assertion (A) is true because glucagon increases the blood glucose level, which is termed hyperglycemia. Reason (R) is also true and provides the exact physiological mechanism for the Assertion. According to NCERT, glucagon is a peptide hormone that acts mainly on the liver cells (hepatocytes). It stimulates glycogenolysis and gluconeogenesis, both of which add glucose to the blood. Furthermore, it reduces cellular glucose uptake and utilisation, preventing glucose from leaving the bloodstream. Together, these acti
