    It was easier than last year's but it was a okay exam
    Now for chemistry f214 ahhhhhh I literally know nothing

    Then 100% UMS was around 50-53 or so.
    Hope this year is similar, I think I got about 49-52 and I want an a*

    Exactly! I didn't realise under the topics Communication, Homeostasis or Energy you needed to know what a mother****ing range bar was. OCR have a duty to test us on the **** that's in the syllabus, and so much of that didn't need biological knowledge. OCR should be embarrassed that they can't even write a paper based on the stuff it's supposed to be. **** them.
    was it range?

    Kupdfer cells breaks down red vlood cells
    And liver makes fetus red blood cell

    I put stem cells and bone marrow

    I completely agree with you! Hopefully the grade boundaries will be quite low as I think most people share the same opinion. The dialysis question stumped me completely. Also my general knowledge isn't great so I completely forgot where red blood cells were made!
    Thats not even in F214, and I don't think that its in AS in a big way either, thats just a biology thing, how were we supposed to know it would come up! Luckily I knew about the bone marrow from other reading but still it was really unfair even if it was only 1 mark.

    Red blood cells are made in the bone marrow

    What did they actually want for the neurone similarities in structure question?
    Writing

    Both have cell body
    Both have dendrites
    Both have axon
    Both can be myelinated (Schwann cells surround axon and secrete myelin)
    Both have voltage gated sodium ion channels/sodium-potassium ion pump embedded in plasma membrane

    Seems to easy, especially the first 3 points, but what else can you really write at all?

    Long answer ATP in aerobic and anaerobic respiration:

    In anaerobic respiration, there is a lower yield of ATP as only glycolysis can occur, hence only net 2 ATP molecules produced per glucose molecule. This is because there is no oxygen to act as the final electron acceptor in the electron transport chain. Hence oxidative phosphorylation, Krebs Cycle and Link reaction do not occur.

    I then basically talked about the reverse process for aerobic respiration, but basically just 'ora' so no extra points really made.

    Would this get the majority of the marks/all marks? What did they want.

    I did the same for anaerobic respiration, there wasn't much more to mention
    Argh completely forgot about the voltage gated channels and myelinated, would I just get three marks for mentioning, axon, dendrites and cell body?

    For the question on why dextrose is added to the dialysis fluid, was the answer to reduce its water potential so that its isotonic with the blood and prevent haemolysis?

    I wrote that then changed it to stem cells; bone marrow right at the end. Kupffer cells break them down, not make them.
