What is insulin's effect on glycogen?
Options
- AStimulates conversion of glycogen to glucose
- BInhibits conversion of glycogen to glucose
- CStimulates conversion of glucose to glycogen
- DInhibits conversion of glucose to glycogen
Correct answer
C. Stimulates conversion of glucose to glycogen
Step-by-step solution
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 utilisation. As a result, there is a rapid movement of glucose from blood to hepatocytes and adipocytes resulting in decreased blood glucose levels (hypoglycemia). Insulin also stimulates conversion of glucose to glycogen (glycogenesis) in the target cells . The glucose homeostasis in blood is thus maint
