*Aerobic respiration requires oxygen, whereas anaerobic respiration takes place in the absence of oxygen.
*Most of the plant and animal cells use aerobic respiration. On the other hand, anaerobic bacteria, yeast cells, prokaryotes, and muscle cells perform anaerobic respiration.
*Aerobic respiration is more efficient than anaerobic respiration. For one molecule of glucose, aerobic respiration produces 38 ATP molecules, whereas anaerobic respiration produces just 2 ATP molecules.
*Aerobic respiration usually takes place in the mitochondria, while anaerobic respiration takes place in the cytoplasm.
*In case of aerobic respiration, the end products are carbon dioxide and water. In anaerobic respiration, the end products are ethyl alcohol or lactic acid, and carbon dioxide.
*Aerobic respiration takes a longer time to release energy. Anaerobic respiration is a much faster process.
