Question
Which of the following represents the action of insulin?
Increases blood glucose level by stimulating glucagon production
Decreases blood glucose level by forming glycogen
Increases blood glucose level by promoting cellular uptake of glucose
Increases blood glucose level by hydrolysis of glycogen
Solution
B.
Decreases blood glucose level by forming glycogen
Insulin decreases the level of glucose in the blood. It acts by stimulating liver cells and muscle cells to take up glucose from the blood and convert it into glycogen. When the blood sugar level drops, the secretion of insulin is suppressed. When the blood sugar level increases, the secretion of insulin is stimulated.
