If you were an anaerobic bacterium and needed to harvest energy,which of the following would be your best option?

Question

Quizplus · Accepted Answer

Anaerobic bacteria do not have access to oxygen for cellular respiration, so their best option is to use glycolysis to break down glucose and then undergo fermentation to extract energy from the resulting molecules. This process is less efficient than cellular respiration, but it can still provide enough energy for survival. Option B (fermentation and cellular respiration) requires oxygen, which is not available to anaerobic bacteria. Option C (Krebs cycle and fermentation) relies on cellular respiration, which also requires oxygen. Option D (fermentation only) is not the best choice because it only allows for the partial breakdown of glucose and does not generate as much energy as glycolysis and fermentation combined.
