Detailed explanation-1: -In short, oxygen debt is a temporary physiological process that occurs after performing strenuous exercise. It happens when the body can no longer distribute oxygen to muscle cells to aid the processes that make them function, resulting in muscular fatigue.
Detailed explanation-2: -In the absence of oxygen, cells generate ATP through glycolysis, which is a common process in both aerobic and anaerobic respiration.
Detailed explanation-3: -In the absence of oxygen, cells perform anaerobic respiration in order to synthesize ATP. During periods of extreme exercise, the skeletal muscles receive limited amounts of oxygen. As a result, the skeletal muscle cells perform lactic acid fermentation.
Detailed explanation-4: -Oxygen debt After exercise, the lactic acid has built up and caused an extra need for oxygen – called the oxygen debt. Lactic acid Chemical produced by the incomplete oxidation of glucose (anaerobic respiration).
