- Normal blood glucose concentration
- Pancreas detects low blood glucose concentration
- Alpha cells secrete GLUCAGON and beta cells stop releasing insulin
- Glucagon binds to receptors on liver cells
- -Glycogenolysis is activated
- -Gluconeogenesis is activated
- - Cells respire less glucose
- Cells release glucose into the blood
- Normal blood glucose concentration

- -Glycogenolysis is activated
- Glucagon binds to receptors on liver cells
- Alpha cells secrete GLUCAGON and beta cells stop releasing insulin
- Pancreas detects blood glucose concentration is too high
- BETA cells secrete insulin and alpha cells stop secreting glucagon
- Insulin binds to receptors on liver and muscle cells
- cells take up more glucose
- Less glucose in the blood
- Glycogenesis is activated
- Less glucose in the blood
- Cells respire more glucose
- cells take up more glucose
- Insulin binds to receptors on liver and muscle cells
