  • High glucose detected by receptors in the islets of langerhans.
    • Glucose enters Beta cells on the islets of Langerhans.
      • Glucose converted to ATP within the Beta cell.
        • Calcium channels open, and Ca2+ enters.
          • Ca2+ causes vesicles to move and fuse with the membrane
            • Veisicles fuse and release insulin into the blood stream via exocytosis.
              • Blood glucose is lowered via negative feedback.
