I have a test on tuesday and am having a hard time determining the difference between the two, if someone could help me understand I'd really appreciate it! Thank you.
*there is a difference, this is a college microbiology class just as background information!

I don't believe there is any difference. Two categories of anaerobic respiration are alcohol and lactic acid, which need to be produced through fermentation.

First things first, anaerobic respiration and fermentation are completely separate pathways. Aerobic and anaerobic respiration involve an electron transport chain in the membrane. In aerobic resp the terminal electron acceptor is oxygen and in anaerobic resp it is something else (e.g. nitrate, sulfate, fumerate, malate, etc). Fermentation, which occurs anaerobically, is a pathway where NADH (or some other reduced electron acceptor-generated by the pathway) gets reoxidized by the metabolites of the pathway. Basically instead of the electron carriers reoxidizing NADH, in fermentation they dispose of electron in an "electron sink," which is then excreted into the medium (e.g. alcohols, solvents, organic acids). Also, this occurs in the cytosol, not the membrane.
