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: -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-3: -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-4: -Assertion :Aerobic respiration is bioenergetically more efficient than anaerobic respiration. Reason: Aerobic respiration takes place in mitochondria, whereas anaerobic respiration occurs in the cytoplasm.
Detailed explanation-5: -Answer and Explanation: Aerobic respiration is more efficient than anaerobic respiration because aerobic respiration produces 38 ATPs for one glucose molecule. Anaerobic respiration produces only 2 ATPs for one glucose molecule.
