Cellular Respiration
is the process
in which food molecules, like glucose, to Carbon Dioxide, and Water.
The equation for this process is:
C6H12O6 + O2 → CO2 + H2O + 38 ATP
This process occurs in two places.

Evolution of Anaerobic Pathways |
It is said that the Anaerobic pathways have most probably evolved very early on in history. The first organisms were bacterias, and they generated their all of their ATP from Glycolysis.
Numbers suggest that it took over a billion years for the photosynthetic organisms to arrive on Earth. They filled the air with oxygen, which triggered the evolution of organisms that used Aerobic Respiration.
Anaerobic pathways are only sufficient for small, uni-cellular organisms. Larger organsims have greater requirements, thus Aerobic Respiration caters those needs efficiently.
