    Was Animals at the top so it couldn't be Kingdom?

    I put:
    PHYLUM
    CLASS
    ORDER
    FAMILY
    Yeah me too. Because animals was already there which is the kingdom so you had to go down from that

    What were the advantages of the 3 domain system over the 5 Kingdom system? I had no clue what to put for that :/. Definitely a harder paper than last year tho, wish I hadn't messed up then now more than ever 😭😭

    would writing about prosthetic groups in the enzymes question get me marks?!!!! because it said ions and I thought about heamoglobin and thats a globular protien and iron ions help it carry out its function so I wrote thats prosthetic group may help enzyme carry out the metabolic process it is involved in :// I don't know if that makes any sense can someone please let me know if this will get me any marks.

    That question was hard. I was writing everything about organic and inorganic cofactors and how they help to increase the rate of enzyme reaction... That question was so hard. Also the question were you had to write how you would carry out the investigation for the water lily plant was really difficult my hopes of getting an A in this paper are gone

    what did everyone write about the glycogen structure and function and the question about tar
    for glycogen:
    1-4 linked glucose chains shorter than starch, it's very compact which makes it good for storage as granules in the liver
    lots of side branches, which allow enzymes that break down the molecule easy access and glucose will be released more quickly
    Advantage to animals because animals are very active so use more energy than other organisms such as plants which have no movement. Also, quick glucose release is an advantage because it allows for sudden strenuous activity such as running away from predators etc.
    Not sure if it's right though, I'm really doubting myself with this exam.

    I would say about 68/100 for an A as that was what it was last year. About equal difficulty. Full UMS probably around 80/100

    Did it ask for advantages or reasons? because I think I wrote reasons :confused:

    I put biodiversity in a habitat, and then biodiversity on a world scale. Not sure tbh

    I thought it was good if you knew all your stuff and had done past papers. A few tricky stuff here and there but overall it was good. Should get above 80!

    Glycogen is readily soluble but still that's only one mark out of seven.

    Yeah I think I mentioned glycogen being insoluble.
    Reading this thread I can just see the marks disappearing one by one, depressing
