| $1.$ | An aerobic respiration takes place using oxygen, inhaled in breathing. | Whereas an anaerobic respiration requires no oxygen. |
| $2.$ | In aerobic respiration, breakdown of glucose results in production of Carbon Dioxide, Water and Energy. | In anaerobic respiration, the breakdown of glucose first results in Lactic Acid and energy then lactic acid break down into carbon dioxide and water. |
