    Meh I didn't like it so much and I think most found it easy in my school- some smoking, DNA replication and immune system would have suited me more :/ probably high grade boundaries now and I seem to do better at more difficult exams!

    it think he alcohol dehydrogenase question was a little tough and some parts of others can't remember. I am in a big dilemma for this 1 mark question of 'which biological molecule does alcohol dehydrogenase belong to' i said protein am thinking this might be wrong

    I think it was supposed to be an enzyme, but enzymes are proteins, so let's hope the mark scheme is generous

    It was an easy exam compared to previous years, the questions weren't that hard the centrifuge Q was random but only 1 mark each and lots of easy marks such as draw hydrogen bonds between bases and why werent water bears discovered till 300 years ago....

    this does mean high grade boundaries though.....

    I got really confused on the last question about the 'water bear'. Was that a prokaryote or a protoctist?

    I really HATED that DNA think where you had to draw it, where did everyone draw their lines???

    And I also didn't understand what the one about the phagocyte was asking so I literally wrote out the entire immune process lol do you think i can get some marks?

    i had to draw 2 hydrogen bonds between a and t and 3 hydrogen bonds between c and g. Also, for the other question you just had to explain the process of phagocytosis ( pathogen engulfed, trapped in phagosome, lysosomes etc), it depends what you have said, give an example if you can.

    Ah I said that the phagocyte engulfs the pathogen by surrounding it with its cytoplasm and then forms a phagocytic vacuole, then the lysosomes fuse with the phagocytic vacuole and release digestive enzymes to break down the pathogen and present the antigens on the surface of the phagocyte - antigen presentation.


    Also yeah i got the hydrogen bonds I meant the test tube thingy where you had to draw the bands :/
