Detailed explanation-1: -The ATP yielded in aerobic respiration is about 38 molecules by complete oxidation of a single glucose molecule. On the other hand, anaerobic respiration produces only 2 ATP per glucose molecule. Thus, the most efficient form of respiration is aerobic respiration.

Detailed explanation-2: -Aerobic cell respiration is roughly 18 times more efficient than anaerobic cell respiration. Your cells require a lot of energy and are dependent on the high efficiency of aerobic respiration. They quickly die if deprived of oxygen.

Detailed explanation-3: -With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration.

Detailed explanation-4: -Aerobic respiration is much more efficient, and produces ATP much more quickly, than anaerobic respiration. This is because oxygen is an excellent electron acceptor for the chemical reactions involved in generating ATP.

Detailed explanation-5: -Since its original observation by Warburg [1], from the standpoint of metabolic efficiency this has been a surprising observation because aerobic glycolysis is far less efficient than mitochondrial respiration in terms of moles of ATP generated per mole of glucose.
