    Might have been two marks - One for identifying the correct test and one for the justification? Can't really remember!
    Actually I remember, surprisingy it was a one marker.

    I put that the extra thing before the fatty acid changed it's shape so it won't be complementary to the enzyme anymore, so no ES complexes would form.
    Same! 😀

    Yes 10 cm^3 of water. How many marks was it?
    I didn't mention the part about 90cm^3 of inhibitor
    Wasnt it 90 of water because it only wanted 1000 of 10000 so it was 100 divided by 10 for the concentration one

    Was it two marks? No idea. And someone else on the page before wrote an answer opposite to mine - No idea who is right.

    I found the paper ok-ish. What annoyed me is how a lot of topics weren't on it. Lets hope the next paper is better.

    10cm^3 inhibitor to 90cm^3 distilled water
    think I put that too, can't even remember aha

    Phosphorylation and active transport
    Active transport and needed for respiration

    10 inhibitor and 90 water is correct. I just got confused when I made my other post on it - Sorry for the confusion

    I think active transport was correct! But respiration makes ATP it isn't used in respiration so i put about how atp is also used in synthesis of molecules such as proteins in ribosomes

    for the question on Alzheimer's and it said why can it fit 2 active sites I said because antigen variability😂, was such a hard paper, what did everyone get for the ror at 10c I got 11

    I said active transport and movement (ATP energy needed in muscle tissues), is that correct?

    Think I got 14.5 really depended on the tangent you drew so the exam board usually has quite a big range for what they'll allow you

    I said that the protein has two regions on it which is complementary to each enzyme

    Yeah pretty sure that's ok

    I put down that they could have similar shaped active sites because only the secondary structure was affected as the only thing different was the fact one was Alpha and one was Beta, so the tertiary structure could be the same so it could be a similar 3D Shape for both.

    I put 10cm3 of the inhibitor and 90cm3 of water to make 100cm3 of the inhibitor with a concentration of 1000 nmol dm-3. Because they started with 10000, so 10000 x 0.1 (90%) = 1000 and therefore you put 90cm3 of water - not the inhibitor. If you do it the other way round you are diluting it by 10% to get 9000 rather than by 90% to get 1000. I think thats right anyway... my maths sucks tbh

    I believe it does - I just realised I got that one wrong!
    Bacteria has a plasmid and free floating DNA
    Viruses have mRNA and Reverse Transcriptase
