4.0 to 7.8 mmol/L
Glycogenesis
Glycogenesis
Conversion of glucose into glycogen for storage
Glycogenolysis
Glycogenolysis
Breakdown of glycogen into glucose
Hyperglycaemia threshold
Hyperglycaemia threshold

Beta cells function
Beta cells function
Detect high glucose; secrete insulin
Alpha cells function
Alpha cells function
Detect low glucose; secrete glucagon
Insulin's two main effects
Insulin's two main effects
Increases glucose uptake & glycogen production
Glucagon's main effect
Glucagon's main effect
Triggers glycogen breakdown in liver
