    how many marks was that question? 1?
    It was only 1 mark

    I thought exactly the same. For some reason I thought the channels may be denatured because they are proteins. Thus K+ channels are not efficient. I'm wrong though. Saying that K channels allowed more K+ to entire explains why action potential was not as great.
    Exactly the same as what I said, K+ channels begin to denature so less k+ diffuse out

    I think the answer was that since glucose is not reabsorbed in proximal convoluted tubule, therefore the solute concentration is higher, which in turn lowers the water potential. As the water potential lowers, the concentration gradient between the tubule and outside is reduced, less water leaves the tubule by osmosis. So the volume of urine increased.
    That is what I put if you look at my original post, I'm just doubting it though

    Oh my bad then. I thought it said humans, but regardless, i just wrote no volume of Oxygen is taken in so RQ value increases to maximum.
    i'm pretty sure it said humans too? i remember thinking that ethanal was bacteria and then wrote down lactate instead because i knew that was humans? i dont know i could be wrong, my brain was fried by the end of that nightmare haha.

    Do you think that's the answer though? Or do you think we were thinking too outside the box, although it seemed pretty obvious to me at the time

    Different question buddy! The RQ question said Yeast cells but you are right about lactate being released in anaerobic respiration in humans!

    I'm not sure, if the channels begin to denature they change shape, so that could mean K+ cannot pass through. Probably too outside the box though. Because the temperature wasn't that high it's not like they disintegrated l, only begin to denature

    Haha, you should be fine then. But just to clarify there is nothing to do with Antidiuretic hormone.

    haha ah goddamn! threw me off cos the next question was about atp and muscles! pray to the wjec gods for low grade boundaries

    Does anyone know the flexibility of the markers for exams like this? Because there was loads of application they'll be getting a lot of different answers. I also saw this thing where the mark schemes that markers get are different to the ones we get online. Apparently the ones online are simplified to contain the core answer. So maybe questions you thought you got disastriously wrong may actually be right, because the questions on that paper today had many different scopes.

    For the RQ value I thought it would decrease because the co2 value would increase and a big number over a small number is a small number????

    Really do you think they could go that low?? I hope so!
    Yes.. compare the one we did today in hindsight .. much harder. So yh .. 49 approx . Trust me ..😉

    How much would you rate the difficulty of this paper out of 5, with 5 as most difficult.

    The value of RQ is infinity during anaerobic respiration because CO2 is produced but O2 is not utilised.

    it was co2 formed/o2 used i think

    big/small = big (e.g. 5/1 = 5)
    small/big = small (e.g. 1/5 = 0.2)

    I feel like both answers a right? I put ADH as diabetics definitely don't release as much ADH as I did a question similar before on a previous paper! But both seem to make sense... I also found it online :
