    Hi guys,

    Can someone help me figuring out this one :
    Each of the following is a correctly paired w/an activated precursor of the polymer, Except one. Which one is this exception?
    1.Sucrose-Dextran
    2.Glucose-Glycogen (true)
    3.Sucrose-Mutan
    4.UDP-glucose-glycogen (this is true, isn'T)
    5.Sucrose-Levan

    I am confused, :oops:

    Thanks in advance

    Ridge and Fateh,

    I am still confused. I found this website, that by the way I believe is very useful, that glycogen is a polymer of glucose,

    http://www.answers.com/topic/glycogen?gwp=19

    ????

    Hey Fateh,

    The answer of your question is for sure ethyl oxide.

    Hi Ridge,

    in dental decks in the microbiology/oral part says that mutan, dextran and levan come from sucrose, so mutan and levan cannot be exceptions.
    It says that an enz splits sucrose into fructose and glucose
    1.- glucose forms dextran
    2.- fructose forms levan

    I am relly comfuse with this q
    It looks that all the answers are correct and there is not one exception

    The answer is mental nerve. The key word in here is CUTANEOUS. The mental nerve supplies the cutaneous portion of the lower lip and chin.
