    I don't know the answer, but I put because blood glucose conc hasn't come down to optimum yet, and so negative feedback hasn't happened yet.
    i said ATP still not fully broken down (or something) so potassium channels remain closed and calcium ions can still enter etc but it is totally wrong i think

    I wasn't sure whether to put 93 or 93.4, because the rest of the column was to 3 significant figures, but it was also to no decimal places. I put 93.4 in the end but I dunno :/
    Oh I didn't think of sig fig, I just assumed that they were all to the nearest whole number...but I don't think bio are fussy about these things are they?

    I put that too if that helps?

    I reckon 41 for an A.
    pretty sure it was asking for a structural difference so i'm not sure if you'd have gotten that even if it is right

    What did everyone put for why insulin is still secreted? I put because it takea a while before all the calcium ions leave the cell via active transport so whilst they're atill in the cell theyll still cause exocytosis even if no more glucose is being taken in

    I don't know the answer, but I put because blood glucose conc hasn't come down to optimum yet, and so negative feedback hasn't happened yet.
    For that I wrote that not all of the calcium ions would have been removed

    If you worked out the top row the answer came to 108.9 and they rounded it to 109, so i rounded up to whatever answer I got 93.4 so 94 or something I can't remember
