are aerobic and anaerobic respiration mutually exclusive
Because B. subtilis contains only menaquinone and not ubiquinone , both aerobic and anaerobic respiration may be activated by ResDE through a mechanism mediated by reduction of menaquinone. This hypothesis is now being tested experimentally. These include the Res system required for both aerobic and anaerobic respiration, a nitrite reductase that appears to function in both nitrogen assimilation and respiration, and the central role of PDH complex in fermentation. Many genes have been identified that are involved in anaerobiosis of B. subtilis. pathway, anaerobic respiration, is also active and the two pathways work in synchrony to supply all the ATP necessary. We discuss the differences in the two forms of energy production and suggest that, although anaerobic respiration can supplement deficiencies in the energy supply in the short- As discussed above, the ResD and ResE two-component regulatory proteins play important roles in both aerobic and anaerobic respiration. At present, two genes and one operon involved in nitrate/nitrite respiration are known to be controlled by ResDE: fnr, hmp, and nasDEF.

Helpful, trusted answers from doctors: Dr. Carveth on what is the difference between aerobic and anaerobic exercise: For all intents and purposes, aerobic and ' cardio' are equivalent . Running swimming , elliptical , bicycling etc. are all exerdises when done for 30 min / day 5 days a week wil increase your aerobic capacity and cardiovascular fitness. What are the differences between aerobic and anaerobic exercise in terms of efficiency on metablolism? Dr. Elden Rand Dr. Rand Variable: Typically aerobic exercise will burn calories during the time of exercise and will cause a temporary increase in metabolism after exercise. aerobic respiration is the complete breakdown of glucose to water and carbon dioxide. Since these products are easily eliminated from the mitochondria – no end product inhibition can occur, and the rate of aerobic respiration depends simply on the supply of oxygen and carbohydrate substrate. Contrary to popular belief, aerobic and anaerobic respiration are not mutually exclusive and, at any 10 one time, a proportion of both aerobic and anaerobic metabolism contributes to the energy requirement of the mammalian cell. Mitochondria NITRATE RESPIRATION. Nitrate is the preferred terminal electron acceptor when oxygen is absent because of its high midpoint redox potential (E′0 = +430 mV). Nitrate respiration and nitrite respiration (described in the next section) are the only anaerobic forms of respiration known thus far in B. subtilis. The genes involved in nitrate and nitrite respiration are listed in Table 1, and possible regulatory pathways are summarized in Figure 1. Involvement of the ResD-ResE two-component signal transduction system in both aerobic and anaerobic respiration in B. subtilis is different from the control of respiration within E. coli, wherein genes required for aerobic and anaerobic respiration are often regulated by the opposing activities of FNR and the ArcA-ArcB two-component regulatory proteins, but sometimes by both regulators (28, 36, 76).
No, the aerobic and anaerobic respiration are not mutually exclusive.
