Question

Which represents the action of insulin

• A. Decreases blood glucose level by forming glycogen
• B. Increases blood glucose level by promoting cellular uptake of glucose
• C. Increases blood glucose levels by hydrolysis of glycogen
• D. Increases blood glucose levels by stimulating glucagon production

Answer 1

Answer: (A)

Insulin decreases the level of glucose in the blood. It acts by increasing the rate at which glucose is transported out of the blood and into cells and by stimulating liver cells and muscle cells to take up sugar from the blood and convert it into glycogen. Insulin is antagonistic to glucagon. When the blood sugar level drops, the secretion of insulin is suppressed. When the blood sugar level increases, the secretion of insulin is stimulated.
