    Not tryna scare people but it's very likely that the exam on Thursday is going to be very difficult...OCR need to prove in this new spec that only the most capable get the A's, not the people who learn it all without a good understanding.
    OCR are moving away from just simply writing down theory answers; they're are going to want you to apply your knowledge to hard situations involving complex practicals.

    I'm really annoyed too that they have not given any good resources at all....just 2 papers really?? and the 2 secret ones...
    Ultimately they will want the same proportions of students achieving each grade, so those who would previously get an A should still achieve one.

    Hmmmmm, just think of all the practicals you've done in the past year and think about the theory behind it.....it's hard to predict bc OCR could literally put anything in......

    Question: When looking in a critical value table, do we always go to 0.05 as the p value in ocr bio, or do we look at other p values too- because in psychology we were taught to only look at 0.05?
    Thanks.

    Ph above or below optimum = enzyme denatured
    Ionic and hydrogen bonds broken - not disulphide though, tertiary structure changes - alter active site - substrate not fit

    Ya the plasmodesmata connects cytoplasm of plant cells, this way water moves through




    Now can anyone answer my question up there in the post!!

    If pH is slightly above or below the optimal pH the enzyme will change shape and not function properly, however if placed back into original pH then it will work again fine. If the pH is way over or below then it will cause it to denature and can't e changed back.
