    for the percentage question i got 56% which is correct as you know from my past paper we had this kind of question
    You sure :eyeball:

    Hopefully chemistry is not like that piece of poo.

    You can't really do as much 'suggesting' in chemistry though.. can you?

    hello guys that paper was very nice and easy! :P partly because of the revision i did in here.
    Remarqable M, what did you get for that percentage question? x

    Realistically, how many marks do you think you lost going through this thread. I'll say about 12.
    idk but in June, i thought i lost about 20 marks, I ended up with 90+% so dont worrrrry!

    can anyone tell me the answers / what they put and thought was right for the folling questions :
    1) over simplification of respiration formula
    2) precautions for photosynthesis experiment
    3) why nerve cells cease at high temperature
    4) tissue lining PCT

    this would be very helpful! very very very unhappy.

    ALSO SOMEONE SAY WHAT THE GRADE BOUNDARIES ARE LIKELY TO BEE
    for 1) dont remember much but from what we see it doesnt tell us to where oxygen <--- link that to oxidative PP ,goes, how is co2 released <-- link that too krebs and link reaction and so on.
    2) 2 edits were: light intensity and other was how long each been exposed. since we know light follows inverse law.
    3) link that ions speed. greater temperature = greater extre k.e
    4) Cortex <_<

    according to wikipedia aquatic animals, such as seals respire under water due to more 02 available in the water also something to do with large surface area. That is what i wrote 2marks out of 3?

    well at least you did learn about excretion and photosynthesis
    aswell we talked alot about nervous system. There was alot of marks on excretion.

    For the seal one I said that the seal had a lot of fat (blubber?) so the lipids are used as a reserve respiratory substrate and hydrolysed to form glycerol and fatty acids. Glycerol --> glucose, etc etc. CoA and fatty acid complex sent to the krebs cycle, ATP produced...
    Is that not relatively correct in some way? :p:

    Seal - 3
    First page - 2
    Pts experiment - 2
    Anticoagulanenetn thing - 1

    And there's probs loads more. I didn't like it at all.. I like it when I can just reproduce facts!

    For the oversimplification of the formula, i put that the formula shows us that only one step takes place but in reality four different stages take place.

    (a) a large total oxygen store relative to body size, and (b) parsimonious use of blood oxygen due to the lowered energy requirements of various organs. During long dives, some organs deplete their oxygen stores, become predominately dependent on anaerobic metabolism, and build up large quantities of lactate

    a) lung capacity essentially
    b) lower metabolic rate
    c) anaerobic respiration

    however, explain why you can't stay underwater for longer than 2 minutes until your lungs beg for oxygen and water floods into them instead.

    Because your brain needs oxygen irrelevant of how much energy your body can supply to it or how much lactic acid you can produce. Thats what makes swimming a lot more difficult that running. yet running you could probably produce more lactic acid due to oxygen debt.
    I didn't say that was the only answer - i was offering it forward as a possible marking point

    1) Oh yeah i forgot about that question.. my face was like.. :eek:
    I chatted something about ATP being produced from ADP and Pi. probs wrong..

    2) I said about controlling variables and repeats?

    3) Proteins would denature so channel proteins (to let na in and K out etc) and pumps wouldn't function correctly

    4) I said Epithelium


    Totally feel free to correct me cuz i don't even knoww

    I HOPE THE BOUNDARIES ARE LOOOWWW!
