    Nope I'm sure it was 93

    Yeah it was 93. It was just one divided by the other value

    If anyone's doing an unofficial mark scheme I'm happy to help out
    Guys pls add anything you remember

    1) Inner membrane
    Stroma
    Granum

    M
    B
    M

    why less ATP generated than theoretical
    ATP used to actively transport pyrivate from glycolysis to Link reaction
    ATP used to actively transport NADH2 from cytoplasm into matrix
    Some protons leak through mitchondrial matrix reducing proton motive force

    how structure of motor n sensory neurone are similar
    Both have cell body with nucleus and mitchondria
    Both have axon
    Both can be myelinated, schwann cells wrapped around

    Anaerobic respiration
    No oxygen- oxygen is final electron acceptor
    Electron transport chain cannot function,
    so link reaction and krebs cycle also stop
    Glycolysis is the only source of ATP

    Secretion of Insulin
    1) Glucose diffuses in, metabolised to ATP
    2) ATP causes potassium ion channels to close, depolarisation
    3) Voltage-gated calcium channles open, calcium ions diffuse in
    4) Ca2+ causes vesicles containing insulin to fuse with cell surface membrane and release insulin via exocytosis

    What cells make red blood cell and the location
    Stem cells
    Bone marrow

    RRT
    93


    Range?
    how peritonal dialyisis differs from haemodalyisis?
    peritoneal needing to be done 4 times a day?
    Shivering in fever?

    I put that perineteal needs to be done more because it doesn't filter/clean the whole blood circulation (doesnt clean all of the blood in the body) and therefore haemodialysis needs to be done less regularly because it takes nearly all of the blood and cleans it all, probably wrong but all i could think of!
    yeah i put this. also put that in peritoneal, you don't have as much blood in contact with the dialysis fluid as you have in a dialysis machine

    Did u guys put a higher percentage of males started RTT or whatever it was? Then used figures to get the 2nd mark
    That's what I did

    56745369[/url]]I mucked up last year in my practicals too and it gave me a B in the end, but i resat them to get an A and thats sorted, well done though!
    Ah fab! Thank you

    "Shivering can also be a response to a fever, as a person may feel cold. During fever the hypothalamic set point for temperature is raised. The increased set point causes the body temperature to rise (pyrexia), but also makes the patient feel cold until the new set point is reached. Rigor occurs because the patient's body is effectively shivering in a physiological attempt to increase body temperature to the new set point." -Wikipedia


    How on earth were we meant to know this.
    Thanks OCR!

    would they accept grana not granum?

    also, i wrote underneath the lines in the big essay question and not on the additional sheet but it wasn't out of the boxes, would that be okay?

    No offense mate but it's pretty obvious, they told you that the fever increases the set point in the text above then it was just a matter of knowing what shivering does to the body and putting 2 and 2 together.

    I think thats a very fair assumption :P
    I don't imagine the crusty OCR examiners considered people of other gender than male or female

    IS THERE ANY WAY we can actually complain to ocr bio about this? im not joking
    People say this every year! You just have to take their s**t!
    Wait until you read the examiner report if you really want to be p**sed off, it will probably say stuff like, "this exam was excellent at discriminating good candidates from weaker ones" or "candidates were expected to answer the question as .... , but they didn't because they were all c**p - it can't possibly be because we write vague, misleading questions"

    I said something similar, I wrote that even after food intake glucose is still entering the body because not all the substances will be broken down at the same time so a prolonged release of insulin would be required. Not sure at all :')
    How many marks was this question? Completely missed the point with it and started talking about diabetes!

    I said this; they told you in the question that the body's normal temperature is raised, therefore the body is going to put mechanisms in place to get its temperature up to this new optimum temperature, such as shivering

    Hahaha, how are we even meant to know that for the exam :'
    thats what i said, so it lowers the conc of dialysis fluid so water(i think its meant to be waste) moves into the fluid by osmosis(then removed)
