  • Active Transport
    • Requires energy to move substances against a concentration gradient
    • Used to absorb substances across a partially permeable membrane
      • i.e. glucose can be reabsorbed in the kidney tubule by active transport
    • Requires the use of energy released in respiration
    • Cells are able to absorb ions from dilute solutions
      • Requires energy to move substances against a concentration gradient
