What is the significance of anaerobic respiration for humans?
It allows us to make energy when our cells are not getting oxygen, but in return produces lactic acid. This is not a significant energy source because it only gives the body 2 ATP unlike aerobic respiration which gives around 25 times that amount. Anearobic respiration is used when you sprint because you rapidly use up energy and don’t have oxygen coming in fast enough to do aerobic respiration, so it makes up for that using anaerobic respiration.
