    What do you think Is likely to come up? I think It is much harder than the old spec.

    Do you think the grade boundaries will be low?

    I'm really not looking forward to this, there's so much to learn and I feel like I know none of it
    It's annoying that the exams aren't split into unit 1 and 2 either

    e.g. Gene mutations, protein synthesis, ATP the genetic code

    Literally learning chapter 6 and 7 today.. It's so long but I've almost got the hang of it. There's so much to learn so I just feel like I always forget the previous stuff whenever I learn something new. I have a feeling there's going to be a bit of application questions about either gas exchange or the cardiac cycle.

    What ****ed me over in the specimen papers we've had for the new specification was how strict the mark scheme was! I literally know the majority of the content but I just don't write answers in the way they want me to 😡 It's so annoying. I've basically just accepted that I'm getting a U in these exams no matter what the paper or the grade boundaries are🙄

    Guys I have a question about non-competitive inhibitors
    If you increase the concentration of non-competitive inhibitors then would this affect the rate of reaction?
    I think it does because- these bind to enzyme at a site other than the active site and when attached change the shape in a way that the substrate cannot bind to it. therefore less enzme/substrate complexes formed?

    Is this reasoning right?? Thank uuu

    You're right. It's also a good note to make that substrate concentration won't affect the rate in this case.

    In paper 1 there'll be an approximate weighting as the following:
    47-51% of AO1
    35-39% of AO2
    13-17% of AO3

    where AO1 is knowledge and understanding (textbook stuff), AO2 is applying scientific knowledge and AO3 is analysing and interpreting info and practical procedures

    Anyone know of anywhere to get new spec questions other than specimen papers or any handy websites for revision?

    Its a new spec so there is only specimen papers to revise from. Thats why the grade boundaries will probably be lower this year as nobody knows what to expect.
