    Can someone please do "importance of glucose for organisms" or the "structure and functions of different animal cells" as someone predicted this!

    Ions in organisms:
    Spoiler:
    Show


    1) Co transport of glucose - Na+
    2) Na+/K+ in maintaining a resting potential and propagating an action potential across a neurone
    3) Ca2+ - synapses
    4) Ca2+ - muscle contraction
    5) Cl- - maintaining WP in lumen of small intestine (link to cholera)
    6) H+ - oxidative phosphorylation in aerobic respiration
    7) H+ - buffer system in blood, linked to nervous control of heart rate
    8) Mineral ions in plants - lower WP in root hair cell, promote water uptake
    9) Nitrate ions, phosphate ions - proteins, DNA
    10) Mg2+ - chlorophyll production
    11) K+ - cell maintenance
    12) Fe2+ - haemoglobin and transport of O2

    You have mentioned:
    10) Mg2+ - chlorophyll production
    Pleasee can you explain this point?

    Importance of glucose sounds pretty closed as an essay title, hasn't been asked on either legacy spec or current spec. Structure and functions of different animal cells probably has a few points in the essays regarding shapes and fit

    Oh ok!

    Could you please outline a few points for the structure and function of animal cells if you have time!

    The importance of proteins in the control of processes and responses in organisms.

    The causes and importance of variation and diversity in organisms.

    Only add it if it adds extra points and not just a summary of what's already been said. The examiners report a few years back quotes "some candidates produced lengthy introductions and conclusions that were no more than synopses of what was going to be or had been written. Clearly this wastes time that would better be spent providing appropriate detail"

    I think basically your intro should just say your umbrella topics in your plan and relate it to the question. One sentence, maybe two; max.

    If you've done something like History and have learned to do a good conclusion I see why not, if you're certain that you've finished of course. I doubt you'd get marked down, but yeah it could be a waste of time if you do it wrong. I use conclusions to sum up something I felt like I 'waffled' on about

    I would love an essay on enzymes or cycles in biology! What is everyone doing to revise unit 1&2, there's only a day left and I barely remember anything.

    I'm not too sure but I'd probably include things like
    - alleles and how differences in alleles arise from mutations, random fertilisation or meiosis (I.e. Independent segregation of homologous chromosomes and crossing over)
    - selection pressures and how variations in phenotype and the wide range of alleles contribute to survival of advantageous individuals (e.g. Selection)
    - natural selection
    - speciation
    - DNA hybridisation
    - genes as genes code for polypeptides and polypeptides control the nature and development of organisms
    - how diversity enables an ecosystem to be more stable

    Dunno just thinking but they're some of the things that immediately come to mind
