Overview of hormonal blood sugar regulation. Insulin and adrenalin promote the absorption of sugar into the cells (from the blood) which leads to catabolic (sugar) metabolism (glycolysis). Insulin inhibits and adrenaline promotes glycogenolysis
Which leads to a reduction in bloos sugar, which should normally be at 5 mmol/l.
Glucagone causes the opposite effects: Gluconeogenesis (and also promotes glycogenolysis)
