Answer:
The correct answer is: C. They will have a lower energy efficiency.
Explanation:
Similar to aerobic cellular respiration, <em>anaerobic cellular respiration </em>uses electrons taken from a fuel molecule to drive ATP production through an <em>electron transport chain</em>. Bacteria and archaea are prokaryotes that survive in low-oxygen conditions and use anaerobic respiration to break down energy.
Methanogens, for example, can employ carbon dioxide as a terminal electron acceptor and produce methane as a by-product. Methanogens may be found in soil as well as in the digestive tracts of ruminants. Fermentation is another anaerobic (non-oxygen-requiring) process for breaking down glucose that is used by a variety of species, including bacteria.
However, <u>the </u><u>glucose breakdown performed by anaerobic respiration isn't complete</u><u> and thus, the energy released is </u><u>19 times less</u><u> than aerobic respiration for the same amount of glucose</u>.
