Write answer in between .Q:A 21-year-old woman with type 1 diabetes mellitus suddenly develops tremors, cold sweats, and confusion while on a backpacking trip with friends. She is only oriented to person and is unable to follow commands. Her fingerstick blood glucose concentration is 28 mgdL. Her friend administers an intramuscular injection with a substance that reverses her symptoms. Which of the following is the most likely mechanism of action of this drug?? A: Activation of glucokinase, B: Inhibition of glucose-6-phosphatase, C: Inhibition of α-glucosidase, D: Activation of adenylyl cyclase, E: Inhibition of glycogen phosphorylasen,  <response>: This is a question about treating hypoglycemia low blood sugar. The patient is described as having type 1 diabetes and developing symptoms of hypoglycemia like tremors, sweating, and confusion during a backpacking trip. Her blood glucose is very low at 28 mgdL. Her friend gave her an injection that reversed her symptoms. The question asks about the most likely mechanism of action of the drug given. Based on the scenario of hypoglycemia in a type 1 diabetic patient, options A, B, and C can be ruled out, as they would lower blood glucose further or prevent glucose absorption. Option D activates adenylyl cyclase, which would stimulate glucose release through glycogenolysis. This makes physiological sense for treating hypoglycemia. Option E inhibits glycogen phosphorylase, which would prevent glycogen breakdown and glucose release. This would not treat hypoglycemia effectively.Therefore, the correct answer is option D, which increases blood glucose through glycogenolysis. This matches the desired effect of rapidly reversing hypoglycemia symptoms.D: Activation of adenylyl cyclase
