Detailed explanation-1: -Aerobic respiration is far more energy-efficient than anaerobic respiration. Aerobic processes produce up to 38 ATP per glucose. Anaerobic processes yield only 2 ATP per glucose.
Detailed explanation-2: -When there is not enough oxygen, pyruvate undergoes lactic acid fermentation. Anaerobic respiration produces less ATP than aerobic respiration due to the incomplete oxidation of the original glucose molecule as a result of not enough oxygen being present.
Detailed explanation-3: -The answer is b. It occurs in the absence of oxygen. Anaerobic respiration occurs for an animal cell when there is an absence of oxygen. When anaerobic respiration occurs for an animal cell, lactic acid fermentation occurs.
Detailed explanation-4: -Although fermentation produces less ATP, it has the advantage of doing so very quickly. It allows your muscles, for example, to get the energy they need for short bursts of intense activity. Aerobic cellular respiration, in contrast, produces ATP more slowly.
