QUESTION 52 An organism is discovered that thrives in both the presence and absence of oxygen in the air. Curiously, the consumption of sugar increases as oxygen is removed from the organism's environment, even though the organism does not gain much weight. This organism O a. is photosynthetic O b. is a normal member of the animal kingdom O c. must utilize a molecule other than oxygen to accept electrons from the electron transport chain O d. only performs fermentation to make ATP
