1)In microbiology, anaerobic respiration means that the ETC is working, but oxygen is not the end electron acceptor. 2) Alternate electron acceptors in anaerobic respiration include nitrogen gas, hydrogen sulfide and methane. » Bacteria that can only use anaerobic respiration grow more quickly than those that can use aerobic respiration. 4) The use of glycolysis only to produce ATP is known as fermentation in microbiology. The purpose of fermentation is to regenerate NADH so that the production of ATP by glycolysis can still occur. 6) A common fermentation pathway is using pyruvate to accept electrons from NADH, thus regenerating NAD+, and also producing lactic acid. 7) Some bacteria can only ferment, some can perform either fermentation or oxidative phosphorylation, and some can only perform oxidative phosphorylation. 8) Organisms that can only ferment grow more quickly than those using aerobic respiration. 9) Fermentation always causes an increase in pH in the surroundings. (0) A chemoheterotroph would use chemical reactions for energy, and organic compounds as a source of carbon. (1) A photoautotroph would use light for energy, and organic compounds as a source of carbon.
