Glucagon, secreted by alpha cells, raises blood glucose through glycogenolysis and gluconeogenesis, and decreases glucose uptake by liver cells.
O glucagon, secretado pelas células alfa, aumenta a glicose no sangue através da glicogenólise e gliconeogênese, e diminui a absorção de glicose pelas células do fígado.
| Front | roles of glucagon |
|---|---|
| Back | alpha cells detect low blood glucose conc and release glucagon into blood, glucagon receptors only present on liver cells/fat cells it inc blood glucose levels by - glycogenolysis (breaks down glycogen store in liver into glucose) - gluconeogenesis (converts AA and glycerol into glucose in liver) - dec absorption of glucose by liver cells |
