An organism is discovered that consumes a considerable amount of sugar, yet does not gain much weight when denied air. Curiously, the consumption of sugar increases as air is removed from the organism's environment, but the organism seems to thrive even in the absence of air. When returned to normal air, the organism does fine. Which of the following best describes the organism? A) It must use a molecule other than oxygen to accept electrons from the electron transport chain. B) It is a normal eukaryotic organism. C) The organism obviously lacks the citric acid cycle and electron transport chain. D) It is an anaerobic organism. E) It is a facultative anaerobe.
