    What kind of questions would come up for digestion?
    I think they would ask specifically about the enzymes digesting. Like in the jan paper they would give you an equation to fill in. So an example would be:
    Sucrose + ____ --> ______ + ______
    Which is water, glucose and fructose.

    Then they would ask stuff about why sucrase can't hydrolyse lactose? etc

    I don't think they would ask you specifically to outline a specific part of the digestive system, rather just chemical digestion e.g. enzymes.

    Can anyone add to my explantation of Phagocytosis:

    (from my textbook)
    1)Chemical products of the pathogen act as attractants, causing the phagocytes to move towards the pathogen
    2) Phagyocytes attach themselves to the surface of the pathogen
    3) They engulf it, forming a vesicle (phagosome)
    4) Lysosomes move towards it and fuse with it, hydrolysing the insoluble molecules to make it more soluble
    5) Soluble products from the break down of the pathogen are absorbed into the cytoplasm of the pathogen
    Surely thats enough for 5 marks. Also phagocytes move along a concentration gradient.

    Not much got to know how to work out the magnification, define resolution and the advantages and disadvantages of each type of microscope.

    Oh my gosh yes! The last part of Jan 2011 was ridiculous. I was doing it as practice and didn't even get half of the marks and normally the NT book is spot on!

    Just limitations/weaknesses. But light microscopes aren't even on the spec if you look - only TEM and SEM.

    It means it doesn't gain marks, but it's not incorrect.

    Yeah but it's pretty stupid putting it in as it is not negatively marked.

    Nope. I think it's just incase the examiner reads it and because it's not on the mark scheme, they assume it's wrong, where as it's not - just not worthy of a mark. So you can link a neutral comment to a correct answer and it be right, or link it to a wrong answer and it'll still be wrong... it's hard to explain, haha my teacher explained it one time.

    Im on to immunology now. Arghh the fun begins :/

    I know, it's correct but just not mark worthy. Another way for AQA to keep marks from us.

    I bet when they create the paper they think, "how can we deceive these poor innocent students *Evil Laugh*". Anyways how is your revision going?

    Haha yeah exactly

    Ermm it's going okay. I feel quite prepared (after I've finished doing this immunology to death) , but I'll go into the exam and they'll always be some stupid question that was miles beyond the spec which no one can prepare for haha. You?

    They will probably link that stuff to cholera disease and absorbing molecules in the small intestine and other parts of the body.
