    Can someone please explain how starch is digested through the body and also the absorption of monosaccharides...Thanks

    Salivary Amylase in mouth hydrolyses Starch into maltose

    Pushed down oesophagus to Stomach, where acidic conditions denature enzymes, preventing further hydrolysis of Starch

    Moves into Small Intestine where alkaline salts are produced to keep PH at neutral. Pancreatic juice mixed with remaining starch, which contains Pancreatic amylase, which hydrolyses remaining starch into Maltose

    Further along the small intestine, epithelial lining produces Maltase which hydrolysis Maltose into Alpha-Glucose

    Absorbed into blood via diffusion and Co-Transport

    However make sure you put hydrolyses glycosidic bonds which is worth a mark

    And so Polyclonal Antibodies are antibodies produced from different B Cells? And all the Polyclonal antibodies are different right?

    Does anyone know if the Production of Monoclonal antibodies has come up in the New Spec papers yet? Could be one of the 5 markers at the end of the paper if it hasn't come up...
    Monoclonal antibodies came up last year I think, and did in jan 2010 too.

    Anyway, best of luck to everyone taking this exam, I'm not looking forward to it at all !

    Hmm, hopefully they won't ask anything on it then

    Then again, if one of the 5 markers at the end involve production of monoclonal antibodies, I may actually know it as i'll be revising it for a quite a while tonight :yep:

    I reckon it'll be something on immunity!
    in june 09 it was on starch digestion on glucose absorption
    and jan 09 it was the difference between a prokaryote and eukaryote, and TEMs

    Which is annoying because I find immunity most difficult!

    Can you list 5 points (bullet points) on the 5 mark questions or does it need to be a paragraph with good English?

    No Problem

    As Chem1stry said above, just remember to add that Glycosidic bonds are broken, and thats the full summary

    I think the longer question are meant to be written in continous Prose. It usually says something about this on the front of the exam paper. I'd do it in paragraphs just to be on the safe side

    chemical tests are usually 1/2 marks. I cant imagine it being a 5 mark question. Its probably likely that its a bigger topic like immunity or enzymes. Thanks for the sugggestions guys. Oh and plasma membrane transport hasnt come up on 5 marker so thats likely!
