Oxygen usage is NOT a characteristic of life.
- Cellular respiration is the metabolic pathway by which aerobic cells can produce energy by using the energy stored in the chemical bonds of foods in presence of oxygen.
- Conversely, there are organisms capable of fermenting foods in anaerobic conditions to produce energy in the form of ATP.
- Moreover, all organisms are composed of one or more cells and they carry out metabolic functions (i.e., reproduction, growth, differentiation, etc).
In conclusion, oxygen usage is NOT a characteristic of life.
