anaerobism

[Lanell]

Anaerobic respiration is a process in which energy from food or stored fat is released through the breakdown of chemical bonds in molecules. It occurs when the bodys energy stores are depleted, such as during exercise or when food is scarce. Anaerobic respiration allows the body to use up its stored energy quickly, but at a high cost in terms of oxygen consumption and carbon dioxide production. It is commonly used by athletes during intense physical activity to fuel their bodies and maintain high levels of performance.
