Want this question answered?
Respiration ---- * areobic respiration which requires oxygen * anaerobic doesn't require oxygen aerobic respiration needs glucose and oxygen. During anaerobic respiration the glucose is only partly broken down to form lactic acid and energy.
I am asking myself the same question, and found this report, which seems to indicate that lactobacillus prefers an anaerobic environment...:Abstract: The growth rate of Lactobacillus plantarum(...) decreased during aerobic incubation (relative to anaerobic incubation). (...) Increased O2 utilization was accompanied by a switch in metabolism which resulted in acetate rather than lactate accumulation in aerobic cultures."Comparison of aerobic and anaerobic growth of Lactobacillus plantarum in a glucose medium", http://www.springerlink.com/content/p18g513007110117/
it is anaerobic because it can make ATP without using oxygen, which is what anaerobic means: without oxygen. :)

Lactic acid and fermentation occur during anaerobic metabolism.
If cells are hypoxic, they may produce lactic acid during anaerobic cellular respiration. Some bacterial cells produce alcohol.
Fast fatigable fibers.
Aerobic Metabolism is the pathway used for exercise
When muscles overexert, the available oxygen may run out and they resort to anaerobic metabolism creating lactic acid which is what causes the soreness felt after exercise.
During a skeletal muscle contraction, the three ways in which ATP is generated are through direct phosphorylation, anaerobic pathway and aerobic respiration. In direct phosphorylation, ADP is phosphorylated by creatine phosphate; in anaerobic pathway, glycolysis and lactic acid formation occur; and in aerobic respiration, 95% of ATP is produced.
When the body runs out of oxygen, it switches to anaerobic metabolism, which generates energy without oxygen. During anaerobic metabolism, glucose is broken down into lactic acid to produce energy. However, this process is less efficient and can only sustain limited activity before fatigue sets in.
During hypoxic conditions when they cannot get enough oxygen.
Metabolism can speed up during adolescence. This is one of the times during a life cycle where the metabolism works faster.
