  • Normal blood sugar
    • The beta cells in the islets of Langerhans in the pancreas secrete insulin which travels in the plasma of the blood.
      • The insulin attaches to receptors on the cell which open gated channel proteins and allow glucose to enter by facilitated diffusion. This happens in muscle and liver cells.
        • The secretion of insulin causes:
          • Absorption of glucose into cells- increased cellular respiration.
          • Glucose--> glycogen glycogenolysis
          • Glucose--> fat
          • Normal blood sugar
    • Alpha cells in the islets of Langerhans in the pancreas will produce glucagon.
      • This will happen in the liver cells.
        • This causes:
          • Glycogen--> glucose glycogenolysis
          • Amino acids--> glucose gluconeogenesis
          • Normal blood sugar
