Answer 2

$</strong><strong>ANSWER</strong><strong> </strong><strong>$

Respiration is a chemical reaction that happens in all living cells, including plant cells and animal cells. It is the way that energy is released from glucose so that all the other chemical processes needed for life can happen. Do not confuse respiration with breathing (which is properly called ventilation).

Aerobic Respiration:

Glucose and oxygen react together in cells to produce carbon dioxide and water and releases energy. The reaction is called aerobic respiration because oxygen from the air is needed for it to work.

Anaerobic respiration:

It 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.
