Detailed explanation-1: -Anaerobic respiration has the advantage of being faster than aerobic respiration and not requiring oxygen for energy conversion. In muscles, for example, when oxygen supply is insufficient, pyruvic acid is converted to lactic acid in order to provide energy during severe activity.

Detailed explanation-2: -Anaerobic respiration is the hallmark of explosive athletes such as sprinters, football players and wrestlers. When you need immediate energy for a short burst, anaerobic respiration provides it without delay. Anaerobic running pushes your heart rate above 80 percent of its maximum, which can be stressful on the body.

Detailed explanation-3: -Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen. If oxygen is present, the pathway will continue on to the Krebs cycle and oxidative phosphorylation. However, if oxygen is not present, some organisms can undergo fermentation to continually produce ATP.

Detailed explanation-4: -Glycolysis (see “Glycolysis” concept) is an anaerobic process-it does not need oxygen to proceed. This process produces a minimal amount of ATP. The Krebs cycle and electron transport do need oxygen to proceed, and in the presence of oxygen, these process produce much more ATP than glycolysis alone.
