    On the bio section of destroyer #145 in 2011 edition,

    the question reads:

    Bacteria derive their energy from:

    a) Krebs cycle
    b) Glycolysis
    c) Electron transport chain
    d) A and B
    e) B and C

    According to the answer key, answer is D.

    Based on the explanation, it should be E right? not D...

    Why E?

    Glucogenic and ketogenic precursors feed into the Glycolysis and Kreb cycle pathways, so D is the correct answer.

    Wait, what?

    They said the answer was D, but in their explanation, it suggest E. They say they do not have mitochondria to do TCA but they can carry out glycolysis and do ETC.

    So shouldn't it be E?

    What are you guys talking about? Bacteria don't have mitochondria to have Krebs Cycle!!! The do Glycolysis and Electron Transport Chain (which could be at multiple sites).

    The answer should be E!

    Don't bacteria do ETC in their cell wall?
