Quizplus · Accepted Answer

Aerobic metabolism is more efficient than fermentation, which is indicated by the increase in the rate of glucose consumption upon the addition of O₂. This suggests that the bacteria switch to aerobic metabolism, which yields more energy from glucose than anaerobic processes like fermentation.
