Aerobic respiration only takes place in the presence of oxygen, therefore it can fully breakdown glucose and produce much more ATP than anaerobic respiration
Aerobic respiration takes place in the presence of oxygen while anaerobic respiration occurs without oxygen. Furthermore, the amount of energy release or ATP produced in aerobic respiration more when compared with anaerobic respiration. Thus, the presence of oxygen in aerobic respiration breaks down glucose all the way to carbon dioxide which release enough energy and produce 38 molecules of ATP while in anaerobic respiration, glucose is broken down to produce just 2 molecules of ATP.
