    hey... i have pretty much finished going over this topic but just need to recap. I can't seem to find any past papers for this unit apart from the specimen one, and all the old spec stuff - surely the majority of it isn't actually relevant to this syllabus? if someone could quote me with the link(s) to some past papers that would be awesome!

    Thanks

    Lol, mate there's 6BI07 and 6BI08 for International students. Since we cannot do coursework, there must be practical written alternative papers to 6BI03 and 6BI06. These are Unit 3B (6BI07, AS) and Unit 6B (6BI08).

    Got it?

    Unit 3B is kind of easy (though I only got a flat B).

    6B is a *****!

    Ok here are the questions our teacher set us about the pre-release material, as promised.

    1. Describe how a neurone can make a muscle 'clench'. (paragraph 3). (3)

    2. In para 6, what would make a simple 'neural circuit'? Draw a labelled diagram to help you. (3)

    3. What are the key issues, both positive and negative, of using animals in experiments to test (para 8) scientific theories of how the human body works? (4)

    4. In para 10, it describes how some neurones are excitatory, whilst others are inhibitory. Explain how this can be the case. (3)

    5. Describe the basic steps involved in inserting a gene (para 17) from rats into fruit flies. (4)

    6. The ChR2 gene codes for a channel protein (para 22). Describe how a channel protein works. (2)

    7. In para 23 a German team managed to express the ChR2 gene. Draw a simple flow chart showing the steps at a cellular level of how genes can be expressed. (3)

    8. Gottschalk (para 26) describes it as a 'proof of concept'. what does this mean? (2)

    9. In para 29 'action potentials are generated'. Describe how this occurs. (3)

    10. Deisseroth's clinical trial (para 36) was looking at area 25 of the limbic system. Discuss the validity of his results.

    11. Gene therapy involves a modified cold virus to insert the foreign gene (para 39). Why are viruses often used as vectors in gene therapy? (2)

    12. Apart from stress (para 43), what are the other key risk factors for cardiovascular disease? (4)

    13. How does the body prevent a neurone from repeatedly firing (para 50)? (3)

    14. What evidence suggests that noradrenaline is not the cause of stress (para 58)? (2)

    15. Why is it important that women should be included in clinical trials (para 67), and why are women often not included in such trials? (3)

    16. Summarise the key findings about why there seems to be sex differences in pain perception (from para 61 onwards). (5)

    17. Why might eating chillis make women suffer more pain than those who don't (para 78)? (1)

    N.B. "para" means paragraph and the number in brackets is the number of marks. Also, for question 4, in my textbook it doesn't have anything about excitatory/inhibitory neurones, just excitatory/inhibitory synapses, so I took it to mean the same thing.

    If you want the answers then I can pm them to you.

    Hope this helps!


    hey! can you PM the answers to me too? thanks a lot!

    Really useful website that someone posted on another thread for Edexcel SNAB biology. Has revision notes for all the units and past papers for all as well!

    Can we take the noted copy of pre-release in or will we get a new copy in the exam?
