    Yeah... i know right .... its from the examstyle questions in the book chapter 10
    ... the answer to The tertiary structure of Haemoglobin allows it to carry oxygen, Explain how.... apperently is this....
    Each polypeptide has a specific 3D shape.... ( this is where im like... crap im soo lacking ) haemoglobin has hydrophillic groups that allow it to mix with blood...
    (Im like aint that a randomn answer... so not what I would put)
