    Just sat the Biology BY1 exam a few hours ago wanted to know what other people thought...
    I Revised solidly for three days straight - My eyes are killing me!
    Personally I found the questions a bit too easy for my liking.
    The essay question wasn't to bad...

    Yeah, i thought it was okay too. Not overly challenging though i know i lost 4 marks for sure for the lactic acid question!
    But if everyone thought it went well....that means grade boundaries are gonna go up dun-dun-dunnnnn:mad: For the essay question I did the enzyme inhibition one!!!! i did this question the night before so yay me!

    What did everyone write for the question on the uptake of phosphate ions? The question with the graph?

    I also did the water potential essay question! The essay wasn't too bad!

    quick question, if you don't mind. What was the question involving the lactic acid. Was it the 4 mark one?

    Well, all my friends said they wrote conc. increases but, I read this online which kinda suggests the concentration should decrease because the curds are denatured proteins so the glucose must be denatured too..right?
    'Milk contains lactic acid bacteria. These bacteria produce
    lactic acid, which acidifies the milk. The reduced pH denatures the milk proteins, casein for example, rendering them insoluble. The curds are the denatured proteins.'

    For the lactic question I think at least one of the marks was stating that the lactic acid is an acid which would mean that the Benedicts solution would not be able work unless it was neutralised with an alkali - I wrote conc decreases I didn't write anything on denaturing tho....:eek:

    Q6d wasn't written well at all- One of my teachers marked these papers, about 1/150 got full marks! Basically, the info given in the question wasn't helpful because the enzymes were immobilised so were therefore more resistant to changes in pH!! How this question passed inspection is unclear, but the mark scheme basically allowed any reasonable attempts at answering, even though the science was wrong:L

    It is only a guess but the properties of water hasn't been for a while, last seen in the January 2011 paper, so it could be that. the cell membrane essay also hasn't been for a while aswell, January 2010. those are my top two but its wjec, you never know what's coming your way cuz they are a bunch of w******

    The essay questions that came up in Jan were enzymes and inhibitors and one about water potential/turgidity etc. Sorry I can't give you the exact questions, I sat the exam and I can only remember what the topics were!
