The mitochondria , found in the cell cytoplasm, are where most respiration happens. Jon Chase explains aerobic respiration. During hard exercise, not enough oxygen can reach your muscle cells.

So, aerobic respiration is replaced with anaerobic respiration. This does not need oxygen for it to happen. Here is the word equation for anaerobic respiration in humans:. Anaerobic respiration produces much less energy than aerobic respiration. The waste product, lactic acid , builds up in the muscles causing pain and tiredness. This leads to cramp. Lactic acid is only broken down when you start aerobic respiration again. Anaerobic respiration happens in microorganisms such as bacteria because they need to release energy from glucose too.

Yeast, which are unicellular fungi, can carry out an anaerobic process called fermentation. Here is the word equation for fermentation:. The ethanol alcohol is useful for brewers and wine-makers, and the carbon dioxide is useful to bakers because it helps their bread rise.
