respiration in human beings identify the kind of element reaction in which the following statement and define each of them
Answers
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.
Here is the word equation for aerobic respiration:
glucose + oxygen → carbon dioxide + water
Anaerobic 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:
glucose → lactic acid
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:
glucose → ethanol + carbon dioxide
