From the picture above you can see that the air entering through the respiratory system will be used for biological oxidation process, which is a process that produces energy by breaking down more complex molecules into simpler molecules, especially the simple sugar molecule is decomposed into carbon dioxide and water vapor. Energy created from the results will be used for biological oxidation processes of life activity, among others, to move, to make growth and development, reproductive processes, and regulate body temperature and other akvifitas life. Well, now you understand why the process of respiration is not important?
This respiration process can take place in two ways, namely respiration
aerobic and anaerobic respiration.
1. Aerob respiration (oxidation)
This process is a solution using the oxygen molecule, the reaction is generally as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O + 675 calories
If you look at the process of chemical reaction produces a lot of energy, amounting to 675 calories. In general, under normal circumstances humans using this method.
2. Anaerobic Respiration
C2H5OH → 2C6H12O6 + CO2 + 28 calories
when the muscles work too hard and excess.
Respiration can take place in three stages.
C6H12O6 → pyruvic acid + 2 ATP + 2 NADH2
b. Krebs cycle
c. Electron Transport Chain
Electron transport occurs in the mitochondria which generate a lot of ATP. Generate ATP reaction involving electron carrier system. In this reaction that is important is NADH, FAD, and specific molecules in respiration, among others, co-enzyme A, flavoprotein, and cytochrome. The end result of the electron transport reaction is H2O.The reaction can be written as follows.
10 NADH + 5 O2 ----> 10 NAD + + 10 H2O + 30 ATP 2 FADH2 + O2 ----> 2 FAD + 2 H2O + 4 ATP
