Question

Is there any significance why anaerobic respiration occurs?Explain your answer

Answer 1

Anaerobic respiration occurs when the amount of oxygen available is too low to support the process of aerobic respiration. 

Answer 2

Anaerobic respiration occurs when the amount of oxygen available is too low to support the process of aerobic respiration. There are two main types of anaerobic respiration, alcoholic fermentation and lactic acid fermentation. During anaerobic respiration, your muscle cells use sugar to make ATP, but they don't use oxygen. This process produces lactate, which is quickly converted to lactic acid, which makes your muscles burn. Lactic acid, as you may have experienced, makes it harder to exercise.
