AlisonNM Posted March 27, 2017 Share Posted March 27, 2017 I have an essay question on one of my assignments and I would love some help or maybe to be lead in the right direction. I'm struggling with this chapter in Microbiology and my instructor is just not helping me understand it! The question is : Is molecular oxygen the only substance that can be used as an electron acceptor in bacterial metabolism pathways? Why? Any help would be greatly appreciated. Know of a website or online lecture I could watch that might help explain? Thanks! Link to comment Share on other sites More sharing options...
CharonY Posted March 27, 2017 Share Posted March 27, 2017 Ask yourself this question: Do all bacteria need oxygen to live? Link to comment Share on other sites More sharing options...
AlisonNM Posted March 27, 2017 Author Share Posted March 27, 2017 I believe I was over thinking this question. So bacteria that doesn't need oxygen can use another organic compound as an electron acceptor? I'm sorry, I'm sure I sound dumb but my instructor has serious confused me on this chapter.

CharonY Posted March 28, 2017 Share Posted March 28, 2017 It does not have to be organic. After all, oxygen is not, either. There basically two basic ways to generate energy without oxygen. Fermentation, where there is not an electron transport system and anaerobic respiration. The latter is the equivalent to use oxygen. You should read up on these definitions and figure out the principles behind either. Link to comment Share on other sites More sharing options...
