Tubular Reabsorption

• What is the 1st function to be affected in RENAL DISEASE?

  Tubular reabsorption
• During tubular reabsorption, the body cannot lose how many mL of water containing substances every minute?

  120 mL
• Renal threshold: Range at which the body stops active transport for substances and the kidney stops reabsorbing them.
• Renal threshold: the plasma concentration at which ACTIVE TRANSPORT stops.
• What is the renal threshold of glucose?

  160-180 mg/dL
• Active transport: movement of substance across cell membranes into the bloodstream by ELECTROCHEMICAL ENERGY. It has a carrier molecule that uses ATP.
• Passive transport: movement of molecules across a membrane by DIFFUSION because of PHYSICAL GRADIENT. It is due to concentration gradient.
