    • What is the equation for Photosynthesis ?

      6CO2 + 6H2O + light energy -> C6H12O6 + 6O2
    • What factors affect the Rate of Photosynthesis ?

      Light intensity / temperature / carbon dioxide concentration / water availability
    • What is the practical that shows the Rate of Photosynthesis ?

      • A light source is placed at a specific distance from the pondweed
      • Leave the pondweed for a set amount of time; as it photosynthesises, oxygen will be collected with a capillary tube and gas syringe.
      • Make sure the temperature is the same and the time it is left
      • Repeat following steps multiple times at different distances
    • What is Respiration ?

      • The process of tranferring glucose into energy in the presence of oxygen.
    • What is Metabolism ?
      • All chemical reactions that occur in an organism / body
    • What is the equation for Anaerobic Respiration ? (Human body)
      Glucose -> Lactic acid
    • What is the equation for Anaerobic Respiration ? (Plants and Yeast)
      Glucose -> Ethanol + Carbon Dioxide
