Answer:
C
Explanation:
If blood glucose is low, insulin is not released into the bloodstream and glucose is not stored as glycogen.
Insulin is only released by the pancreas when the glucose level in the bloodstream rises beyond the setpoint. When released, insulin converts excess glucose to glucagon and the latter is stored in body muscles and the liver. When required, that is, when the glucose level in the bloodstream falls beyond the setpoint, the glycogen is converted back to glucose by glucagon enzyme released by the pancreas.
The correct option is C.
