AIIMS 2017 Zoology Hormonal Regulation of Blood Sugar MCQ Question
Which of the following is the action of insulin?
Blood glucose level increases by hydrolysing logistic glycogen in liver
Decreases blood sugar level by forming glycogen
Increases blood glucose level by stimulating glucagon production
Increases blood glucose level by promoting cellular uptake of glucose
Correct Answer
Detailed Explanation
Option C is incorrect because insulin actually decreases blood glucose levels by promoting the uptake of glucose into cells and stimulating glycogen synthesis in the liver, not by increasing glucose levels. Insulin facilitates the conversion of glucose to glycogen (glycogenesis), which lowers blood sugar levels (option B). Option A is incorrect as it describes the action of glucagon, which increases blood glucose by hydrolyzing glycogen (glycogenolysis) in the liver. Option D is also incorrect because while insulin does promote cellular uptake of glucose, it does not increase blood glucose levels; instead, it lowers them by enhancing glucose utilization and storage.
