    Do you think if you wrote carbon and oxygen for the first question you would lose marks? I know in some of the mark schemes it will only allow the atomic symbol?

    I think because it gave you a displayed formula and told you to fill in the gap, you were obliged to give the chemical symbol as opposed to the name. However I'm sure it'd be fine, though surely it's easier to put a C or an O rather than carbon and oxygen

    Because in some questions it specifically says chemical symbol. Whereas that one just said name the atom or group. So im not sure what it wanted specifically

    Well, I would've thought the chemical symbol would be more appropriate seeing as X, Y and Z were placeholders for carbon, oxygen and hydrogen in a displayed formula.

    Well thats what I thought. But said name the atom or atom group. But as it didn't really specify which one it wanted. Least id get one mark for saying OH (hydroxyl) haha

    got this prediction from student room what do you think ?
    F214:
    Excretion
    - ornithine cycle
    - (possibly) cause of respiratory acidosis
    - detoxification
    - selective reabsorbtion

    Photosynthesis
    - experiments (most likely an application question)

    Communication
    - maintaining a resting potential
    - local currents
    - myelination (benefits)
    - adrenaline (use of first and second messengers)
    - control of heart rate

    Respiration
    - coenzymes (used where)
    - oxidative phosphorylation & evidence for
    - anaerobic respiration
    - respiratory substrates
