A Bacterium That Only Possesses the Ability to Ferment Obtains

Question

A bacterium that only possesses the ability to ferment obtains energy
A)by glycolysis only.
B)by aerobic respiration only.
C)by fermentation or aerobic respiration.
D)only in the absence of oxygen.
E)only in the presence of oxygen.

Accepted Answer

A bacterium that only possesses the ability to ferment obtains energy by glycolysis only. Fermentation is a form of anaerobic respiration that only uses glycolysis to produce ATP. It doesn't involve the use of oxygen or the electron transport chain, which are required for aerobic respiration. Therefore, the bacterium cannot obtain energy by aerobic respiration or other forms of respiration that require oxygen.
