    for the light intensity question, wouldnt you talk about how light intensity is no longer the limiting factor and so c02 or something else must be - then explain this in terms of the calvin cycle?
    You're wrong. It asked for it in terms of biochemistry.

    I labelled the chloroplast AND the mitochondria wrong. They were easy too.

    Yes but also in that question we were told fever increases body temperature. Hence you would normally want to reduce temperature back to optimum via negative feedback. So why shiver if this increases temperature?

    I read the question as the fever causes the set temperature to increase, and therefore the body feels the need to increase its internal temperature which is why it would shiver

    Yes, so as he said, you would talk about CO2 being the limiting factor and then talk about how limiting CO2 is effecting Calvin Cycle no? RuBP+CO2 reaction has a lower rate when CO2 concentration is lower. This is talking in terms of biochemistry?

    I put CO2 concentration as less carbon fixation in calvin cycle, so less glucose and/or amino acids produced

    I also put number of photosystems as they would all be saturated after a while

    Sweating decreases temp, shiver brings it back to normal

    I put shivering increases temp so unfavourable conditions for pathogen and they die. I think the above is correct

    So increase temperate further to kill the pathogens/denature their enzymes

    Yeah that's right. Just mentioning limiting factors won't get you the mark.

    i did it like that as well, with the calvin cycle etc

    no, biochemistry includes the calvin cycle and the fixation of c02, inclusive of RuBP - I don't know what you're idea of biochemistry is! you would have also been able to argue temperature too, given that optimum temp may not have been present, reducing the ability of Rubisco to work and form ESC's. So I know youre wrong....it's more about if anyone else has any other better sugestions
