    I need to finish module 1, 2, 3 and 4

    I revise by making notes then memorising them, a month is ages to do that!
    Yeah true, but I don't know why I'm in panic mode:/ oh well... just one day of relaxing then I'll have to start properly.

    Guys, how long do you think it takes to do module 3 and 4 from scratch? and then I need to revise it all the modules and do the papers. I'm hoping a solid week will do it at most?

    hey all
    i know it's christmas and all, but if there is anyone that can clarify the detoxifcation of ethanol for me, i'd be very grateful

    I'm using the Heinemann textbook - page 41.

    In the text, it basically says:

    Ethanol is broken down by the action of the enzyme ethanol dehydrogenase. The resulting compound is ethanal. This is dehydrogenated further by the enzyme ethanal dehydrogenase. The final compound produced is ethanoate (acetate), which is combined with coenzyme A to form acetyl coenzyme A.

    But in the diagram below the text, it shows ethanol to ethanal to ethanoic acid to acetyl coenzyme A. I presume they mean that ethanol is turned into ethanal into ethanoic acid and then into acetate...? In the text, where it says "the final compound produced...." they seem to have ignored it being turned into ethanoic acid first?

    I know this is a minor point, but I'll rather check than get it wrong

    I'm pretty sure acetate, ethanoic acid and ethanoate are all the same thing. The book isn't very clear on this.

    Well acetate and ethanoate are the same thing, but ethanoic acid isn't. Guess it's turned into ethanoic acid then into acetate/ethanoate... that's how it's normally done in chemistry - (not sure if you do chemistry or not )

    i do chemistry as well. In biology they often call ethanoic acid as ethanoate/acetate and lactic acid as lactate which technically is not correct but biology we need to use those

    There is very little difference in terms of structure between acetate and ethanoic acid. Acetate being CH3COO- and ethanoic acid being CH3COOH. I think this can be overlooked in biology.

    Just revising respiration and am wondering how much I should write in my notes for the learning outcome "evaluate the experimental evidence for the theory of chemiosmosis"? If anyone knows of any examination questions which assess this learning outcome, they'd be really useful too.
    Hope revision is going well for everyone!

    Oh, and I just found this on the internet. It's a powerpoint covering the Photosynthesis and Respiration topics: http://www.franciscombeacademy.org.u...dules3and4.pdf
