Which respiration (aerobic or anaerobic) is more efficient and why?
Answers
Answer:
anaerobic because it can take place in the absence of oxygen
Answer:Anaerobic cell respiration (glycolysis + fermentation) produces 2 ATP/glucose consumed. Aerobic cell respiration (glycolysis + the Krebs cycle + respiratory electron transport) produces 36 ATP/glucose consumed. Aerobic cell respiration is roughly 18 times more efficient than anaerobic cell respiration. Your cells require a lot of energy and are dependent on the high efficiency of aerobic respiration. They quickly die if deprived of oxygen.
Overall, aerobic respiration converts about 40% of the available energy of glucose into ATP. The remaining 60% is lost as heat and helps to generate your relatively high body temperature. 40% efficiency may seem poor but it is several times more efficient than the best automobile engines.
