High blood sugar Pancreas
↓ ↓
Pancreas Secretion of
↓ glucagon
Secretion of insulin ↓
↓ Glycogen breaks down
Intake of sugar to glucose
by liver cells
Step-by-step explanation:
The body must maintain the concentration of blood glucose within narrow limits.
After breakfast, Claire has high blood sugar levels.
A HIGH blood glucose level stimulates the pancreas to secrete insulin.
Insulin stimulates various cells to absorb glucose from the blood and the liver to absorb glucose and convert it to glycogen.
The net effect is that her blood glucose levels drop to the normal range.
After exercising at the gym, Claire's blood glucose level will be low.
A LOW blood glucose level stimulates the pancreas to secrete glucagon.
Glucagon stimulates the liver to break down the stored glycogen to glucose and release it into her blood stream.
Her blood glucose levels again return to normal.
