A bacterium was grown in two test tubes filled with media rich in glucose. One tube was sealed to produce anaerobic conditions,

and the other was not. A third uninoculated, unsealed tube was used as a control. Glucose utilization by this bacterium causes acid production, which is indicated by a lightening of the media color. If the bacterium is able to produce ATP only by aerobic respiration, we expect lightening of media in _____

Answer:

the unsealed tube only

Explanation:

Note that one of the tube was sealed while the other was unsealed. The sealed tube automatically is deprived of oxygen and as such bacteria there use anaerobic means to respire.

Since ATP is produced by Aerobic means, the unsealed tube would be the one that would light up, because of the availability of Oxygen.
