Anaerobic respiration occurs because aerobic respiratory only produces a small amount of ATP (2 ATP) and because oxygen is consumed quickly in tissues. Anaerobic respiration produces a high amount of ATP and is particulary important in tissues such as muscles during streneous exercise.

What happens in respiration reactions if no oxygen is present?

This is when anaerobic respiration takes place. It is respiration without using oxygen. However, when anaerobic respiration takes place, lactic acid is produced and accumulates until the muscles cannot work any more. This is why anaerobic respiration can not happen for very long. After anaerobic respiration, the person usually has to breathe heavily in order to break down the lactic acid and to 'pay back the oxygen debt'.
