Final answer:
Aerobic respiration is favored over anaerobic respiration because it produces more energy, is more efficient, and can sustain ATP production for longer periods of time.
Step-by-step explanation:
Aerobic respiration is favored over anaerobic respiration for several reasons. Firstly, aerobic respiration produces more energy than anaerobic respiration. With oxygen, organisms can break down glucose all the way to carbon dioxide, which releases enough energy to produce up to 38 ATP molecules.
In contrast, anaerobic respiration only releases enough energy to make two ATP molecules. Secondly, aerobic respiration is more efficient and produces more ATP per molecule of glucose compared to anaerobic glycolysis. Finally, while aerobic respiration is slower than anaerobic respiration, it can sustain ATP production for several hours or longer as long as the fuel supply lasts.
