This happens in composting, for example. However, anaerobic respiration does not produce or arise as many ATP (System). In some cases, it's a 'backup plan' when oxygen is absent, and in other cases, they thrive that way. Anaerobic respiration is the metabolic process in which oxygen is absent, and only the stage of glycolysis is completed. Other organisms may use the ferric ion as an electron acceptor. For vigorous exercise our heart and lungs would not be able to get sufficient oxygen to our muscles in order for them to respire. The one thing that they all have in common is the use of an electron transport system in a membrane and the synthesis of ATP via ATP synthase. These microorganisms are found in soil and in the digestive tracts of ruminants, such as cows and sheep. If oxygen is not used at all, the process is called fermentation. In aerobic organisms undergoing respiration, electrons are shuttled to an electron transport chain, and the final electron acceptor is oxygen. Desulfovibrio desulfuricans is a sulfate reducing bacterium. In general, organisms that perform this process reduce nitrates (No 3 - ) to nitrites (No 2 - ) By the enzyme nitrate reductase. 4.
