3.1.6 ATP

    Cards (7)

    • Aerobic respiration of glucose:
      • oxygen + glucose -> water + carbon dioxide
      • 602 + C6H12O6 ->6H2O + 6CO2
    • Is aerobic respiration of glucose endothermic or exothermic?
      Exothermic
    • What dose ATP stand for?
      Adenosine Triphosphate
    • ATP has 3 phosphate bonds which are unstable (they have a low activation energy which means they are easily broken). When they do break they release a large amount of energy.
    • Once ATP is made it diffuses into the part of the cell that needs energy. The energy is released via a hydrolysis reaction which breaks ATP down into ADP (adenosine diphosphate) and inorganic phosphate (Pi)

      ATP +H2O ⇌ ADP + Pi + energy
    • ATP cannot be stored or transported between cells so has to be made continuously in the mitochondria of cells when required.
    • The inorganic phosphate released during the hydrolysis of ATP can be used to phosphorylate other compounds, often making them more reactive.
