What type of respiration requires oxygen?

Aerobic respiration is the process that requires oxygen to produce energy. During aerobic respiration, glucose is broken down in the presence of oxygen to generate carbon dioxide, water, and adenosine triphosphate (ATP), which is the energy currency of the cell. This method of respiration is more efficient than anaerobic respiration because it yields a higher amount of ATP per molecule of glucose consumed.

In contrast, anaerobic respiration occurs in the absence of oxygen and results in the production of less ATP. Fermentation is a form of anaerobic respiration that occurs in certain organisms and typically results in the production of alcohol or lactic acid. Phosphorylation, while involved in energy transfer processes, does not directly refer to a type of respiration. Therefore, aerobic respiration is distinguished by its requirement for oxygen, emphasizing its role in energy production within aerobic organisms.
