If given the choice of using oxygen or not, which should a faculative anaerobe preform
A. Use oxygen since aerobic metabolism provides more ATP per molecule of carbohydrate broken down than anaerobic metabolism B. Not use oxygen since it is a faculative anaerobe, it doesn't tolerate oxygen well C. Use oxygen because aerobic metabolism is easier D. It doesn't matter; both process will produce the same results |
