    Was it not you who wrote that ATPase doesnt directly break down ATP and water does?

    I dont understand this foolishness. Your telling me that the enzyme for ATP doesnt directly break down ATP. So I guess amylase doesnt directly break down starch and maltase doesnt directly break down maltose and protease doesnt directly break down proteins? Damn. You sure?

    What are people's grade boundary predictions? I personally didn't find the exam difficult but I didn't find it easy either!

    Nah I think if we had a week before the unit5 exams after unit 4 exams in general I would have done miles better in them. I have literally had one exam everyday since last week. I do maths, chem, bio, physics, because of this I think I have missed the A* in all those subjects. In biology it will depend on boundaries, God and the examiners mercy.
    same here... I do the same as you apart from chem... I do maths, econ and biology... guess it's harder for you since you're doing four...I hate exams on consecutive days...

    So question. I focused mainly on section A so for the essay, 10a, I wrote about two and a quarter pages. The main points were endotherms, ectotherms and behavioural responses to heat ect.
    Respiration, control of the cardiac cycle through homeostasis, action potentials, a bit on receptors and a bit on co2 effect on haemoglobin to qualify my control of the cardiac cycle. I am a tad worried that my essay may not have contained enough. However, the points I did make were rather heavily detailed and I made sure to relate them back to the question.

    What do you guys think?
    I wrote about the same stuffff, didn't go into detail on respiration, briefly mentioned at the end about plants and IAA for photosynthesis and about shivering/sweating and that's about it, although I filled every page with my humongous writing haha

    I wasn't entirely sure for the first question, I know I got the first one wrong because I put anisotropic band but I think it was actin, then the second I put ATPase, then the third I put troponin instead of tropomyosin but it should be tropomyosin right? Oh dear
    I put tryomysin at first but when I was checking my answers I realised how stupid that sounded.
