    I was under the impression that the ETC is common to both aerobic and anaerobic respiration. However, DAT Destroyer #8 says C is the answer - what am I missing?

    For anaerobic respiration, the ETC is never utilized. If no O2 is present, which is the final electron acceptor in the ETC, then it goes to anaerobic respiration which just converts pyruvate to either ethanol or lacate.

    im not sure what the context of the question is, but i do believe that anerobic organisms/ conditions may still use an electron transport chain. However, oxygen is not the final electron acceptor!

    Glycolysis is utilized in aerobic and anaerobic respiration. ETC isn't used in anaerobic respiration. the purpose of anaerobic respiration is to generate NAD+ so glycolysis can continue

    Aerobic and anaerobic respiration both use the ETC. Aerobic respiration uses oxygen as the electron acceptor while organisms such as methanogens (which use CO2 as e- acceptor to produce methane) or sulfur bacteria (which will use SO4 to produce HS) use non-oxygen molecules that are still in an oxidized state. The anaerobic conditions which do not use the ETC (lactic acid and alcohol production) are the result of fermentation processes.

    2011 Destroyer.

    One says ETC is not used in anaerobic respiration, and the other says ETC is used....well that's confusing.

    I thought the ETC is used in anaerobic, however, only 2 ATP are made because of no Oxygen as electron acceptor; whereas 38 ATP are made with Oxygen as final electron acceptor.

    there can't be an ETC with anaerobic respiration, because you need acetyl coA (ideally) to start the krebs cycle, and after the krebs cycle, you can start the ETC
