    1. Theoretically, it requires two NADHs or two FADHs (protons and electrons donors) for every half molecule of O2 (the electron acceptor) to be reduced to one molecule of H2O, represented as follows:
    2 H+ + 2 e- + ½ O2 ---> H2O

    ===> This paragraph is from Achiever, but do you agree that?
    I think "ONE" (NOT TWO) NADH or FADH for every half molecule of O2 to be reduced to H2O is enough. RIGHT?

    2. Golgi manufactures certain polysaccharides ???
    I think Golgi can add sugar group to proteins, but cannot make polysaccharide itself. right???

    3. Which of the following molds classified under kingdom Protista lack flagellated stage(s) in their life cycles?
    I. Plasmodial slime molds (Myxomycota)
    II. Cellular slime molds (Acrasiomycota)
    III. Water molds (Oomycota)
    ==> do we have to memorize this kind of details?
