(2)	Cellular+respiration+–+an+overview

Cellular respiration is the process which food is broken down by the cell to produce ATP molecules which is energy. Cellular respiration take carbohydrates, breaks them into glucose molecules. Then glucose is used up to produce energy-rich molecules such ATP molecules. The chemical equation of cellular respiration is

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa C6H12O6+602==>6CO2 + 6H20 + energy

This equation also known as one glucose molecule plus six oxygen molecules produces six carbon dioxide molecules, six water molecules, and approximately 36-38 molecules of ATP. I found this image here: [] An introduction to Cellular Respiration: media type="youtube" key="2f7YwCtHcgk" height="315" width="560" Aerobic respiration is when cellular respiration takes carbohydrates and break then into glucose molecules and the glucose is used to produce ATP molecules. Aerobic Respiration requires oxygen. Aerobic Respiration happens when glucose reacts with oxygen. The chemical equation of aerobic respiration is

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa C6H12O6 + 6O2-> 6CO2 + 6H2O + energy

The advantage of aerobic respiration is that its more efficient in producing energy; aerobic respiration is used as a fuel source to carry out reactions. The disadvantage of aerobic respiration is presented only when there's energy. Y yu no work!? Anaerobic respiration does not require oxygen. It happens when energy is needed for aerobic oxygen. The chemical equation of anaerobic respiration is glucose → lactic acid (+ energy). The advantage of anaerobic respiration is energy is being produced. The disadvantage of anaerobic respiration is less energy is being produced as anaerobic respiration doesn’t need oxygen.


 * How can respiration be **** measured? **

The rate of respiration is the number of breaths per minute. To measure respiration, locate an area around the person/subject where the chest rises and falls. When you have located the area, all you have to do is count either the number of breaths in OR out (not both) in one minute. It is easier to count the rises of the chest than the falls.
