Hey everyone,
Was wondering: Why does Anaerobic Respiration Occur in Muscles During Exercise, including talking about oxygen debt?
Lol, revision underway but can’t think of a way to word an answer including talking about the oxygen debt.
While we’re at it, can anybody define oxygen debt?
GCSE level
Thanks!

When we exercise, the muscles contract. This requires energy, which comes from the breakdown of ATP into ADP and a phosphate. ATP is produced by respiration. Initially, whilst there is sufficient oxygen being delivered to the cell by the blood, aerobic respiration takes place. However, when there is not enough oxygen for aerobic respiration to occur, anaerobic respiration occurs instead, which produces less ATP. After exercising has stopped, lactic acid has been produced, and oxygen is needed to break this down in the liver. Therefore, excess oxygen is needed to breakdown the lactic acid produced, and also for aerobic respiration to continue. This excess oxygen is the oxygen debt.
