Co-Transport

Cards (6)

  • 1st Step of Co-Transport of Glucose
    Na^+/K^+ pump operates actively using ATP to transport Na^+ ions out of the cell to create a Na^+ concentration gradient
  • 2nd step of Co-Transport of Glucose
    Na^+ diffuses into the cell passively through facilitated diffusion. Glucose passes through the same protein channels and so is co-transported with Na^+
  • 3rd step of Co-Transport
    A high concentration of Glucose is in the Epithelial Cell, so glucose can move out the cell into the blood through facilitated diffusion
  • How does Na^+/K^+ pump work?
    Active Transport
  • How does Na^+ move across cell membrane?
    Faciliated Diffusion
  • How does Glucose move into the cell?
    Co-Transport through the same protein channels as Na^+
