  • Sodium ions actively transported out of epithelial cells by Sodium-Potassium pump into blood, Sodium ions diffuse into epithelial cells against concentration gradient, Na+ ions flood back in and couple with glucose, Glucose passes into blood plasma
  • Sodium ions actively transported out of epithelial cells by Sodium-Potassium pump into blood, Sodium ions diffuse into epithelial cells down concentration gradient, Sodium ions flood back in and couple with glucose, Glucose passes into blood plasma
  • Glucose ions actively transported out of epithelial cells by Sodium-Potassium pump into blood, Glucose ions diffuse into epithelial cells down concentration gradient, Glucose ions flood back in and couple with Sodium, Sodium passes into blood plasma
