“Anaerobic respiration is only used when aerobic respiration is not an option.”
Best argument for this claim:
Anaerobic respiration is a less efficient process compared to aerobic respiration. Cells prefer to use aerobic respiration because it produces more ATP (energy) per glucose molecule. However, when there is a lack of oxygen available, such as in anaerobic environments, cells resort to anaerobic respiration as a backup option to produce some ATP, albeit in smaller quantities.
Best argument against this claim:
Anaerobic respiration can occur even when aerobic respiration is possible. While aerobic respiration is more efficient, some organisms, like certain bacteria and yeast, are capable of undergoing anaerobic respiration even in the presence of oxygen. For example, during intense exercise, muscle cells switch to anaerobic respiration temporarily to meet the increased demand for energy. Therefore, anaerobic respiration is not solely a "last resort" but can be used in various scenarios.
