The type of respiration a cell performs—either aerobic or anaerobic—depends primarily on the availability of oxygen.
When oxygen is available, cells perform aerobic respiration, which takes place in the cytoplasm and mitochondria.
Conversely, in the absence of oxygen, cells perform anaerobic respiration, which occurs only in the cytoplasm.
Aerobic respiration is common in plants, animals, and many types of bacteria, whereas anaerobic respiration occurs in certain bacteria and fungi. Even our muscle cells carry out anaerobic respiration when the oxygen supply is insufficient.
A key difference is that aerobic respiration completely breaks down glucose into carbon dioxide, water, and energy in the form of ATP.
In anaerobic respiration, glucose is broken down into lactic acid and ATP in animals or ethanol, carbon dioxide, and ATP in yeast.
Another significant difference is in energy yield. Aerobic respiration produces 36-38 ATP molecules per glucose, whereas anaerobic respiration generates only 2 ATP molecules.
