  • Active Uptake
    • Active uptake is the movement of molecules form an area go LOW concentration to an area of HIGH concentration.
    • This requires energy since molecules are moving against the concentration gradient
    • Oxygen is also required for aerobic respiration (needed to produce the energy for active transport
    • Active uptake requires eery which is generated by respiration the more oxygen gas there i available the after respiration takes place releasing more energy
      • Th emore energy is released the faster the rate of active uptake, absorbing more nitrates into the root hair cell
    • Waterlogged soils have less oxygen
