    Can't find any threads for this exam. How much have people revised and what techniques are you using to remember things? Are there any topics you think may come up like for the 5/6 mark questions?

    I've revised a fair bit, starting to feel ready to sit the exam now.
    Doing tonnes of past papers today, but I've got a few days to revise.
    Using mind maps, diagrams and flash cards.
    Hoping for questions on; control of the cardiac cycle, phagocytosis, the immune response, electron microscopes as they're all relatively easy for me.
    Hoping there won't be too much on organelles

    Thanks

    organelles always come up like a 2 mark on name x and what is its function and they haven't asked about ultracentrifugation or cell fractionation for a while so maybe revise those

    What could they ask about electron microscopes ?

    Just advantages (of TEM)
    : higher resolution
    : can see structure of cell (organelles)

    or disadvantages
    :cannot scan surface

    I'm really confused, so there only 1 type of antibodies on 1 type of B cells but there are many different receptor molecules on T cells, is that right?

    Just write the word specific and you'll probably get the marks lol..

    umm I'm not entirely sure what you mean though in all seriousness...

    usually they ask why would they use an electron microscope which is an easy two marks to gain:

    1. You get a high resolution
    2. For a short wavelength of light

    I believe there are T cells and these have receptors which are specific to certain antigens.
    these antigens can be found on the surface of phagocytes which have just undergone phagocytosis. Once the helper T cell finds the correct antigen, it will multiply by mitosis to form clones, these clones will:
    -develop into memory cells
    or
    -stimulate phagocytes
    Or
    -stimulate B cells
    or
    -kill infected cells

    you don't need to know it in that much detail for unit 1, you just have to know that a T cell has a receptor

    I revised everything, but tbh I'm quite nervous. I really want to get an A in this. Anyway yesterday, I made a list of 5 mark question that came up since 2010.. and noticed that some of them are the same questions but in a different form.. So they could repeat one and if you've done enough past papers, you'll be able to do it Good luck x

    I've got the exam in 5 hours -.- I'm still not asleep because I'm worried I'm missing out stuff.
    I've just done all the past papers
    Ultracentrifugation hasn't come up - so it may come up on this exam
