Which of the following represents the action of insulin?
-
- Increases blood glucose levels by hydrolysis of glycogen
- Increases blood glucose levels by stimulating glucagon production
- Decreases blood glucose levels of forming glycogen
- Increases blood glucose level by promoting cellular uptake of glucose
Correct Option: C
Insulin is a peptide hormone, which plays a major role in the regulation of glucose homeostasis. Insulin acts mainly on hepatocytes and adipocytes (cells of adipose tissue), and enhances cellular glucose uptake and utilization. Insulin also stimulates conversion of glucose to glycogen (glycogenesis) in the target cells.
