    Hmm.. i'm seriously starting to question the spec now.
    There are things in the book not mentioned in the spec; such as beta oxidation
    do we still need to know these things?

    Ok I have just revised all of Communication and Homeostasis and I am planning on revising the Kidney section before I go to sleep.
    Then I will quickly go over photosynthesis and respiration tomorrow morning.
    Anyone think this is enough revision? I know I've left it bit late..

    beta oxidations is just a pathway that breaks down fatty acids into acetyl (2C) groups

    Isn't oxygen debt something like the amount of oxygen you need to take in (by breathing) to break down the lactic acid produced by anaerobic respiration,,

    Animals produce lactate, which acts as the hydrogen acceptor for reduced NAD, so pyruvate can be oxidised.
    Plants produce ethanol, which acts as the hydrogen acceptor for red NAD.

    Oxygen debt is when there is insufficient oxygen in the lungs.

    Dunno if either of them are right, haven't got onto anaerobic resp yet

    Same goes for them too
    Pyruvate => ethanal => Ethanol .
    under the work of enzyme ethanal dehydrogenase, and ethanol dehydrogenase latter accepting H atom from nad.
