Aerobic and Anaerobic Metabolism
Respiration:
Glucose is the most widely used respiration substance.
During respiration, the stored energy is glucose is gradually released through its controlled oxidation. The released energy is stored by forming ATP from ADP. The entire process of respiration can be represented by the following equation.
C6H12O6 + 6 O2 +6H2O gives 6CO2 + 12H2O + free energy
Kinds of respiration:
Based on this metabolism. Based on the availability and utilization of oxygen, two kinds of respiration occur. They are aerobic respiration and anaerobic respiration.
Aerobic respiration:
In this aerobic metabolism, the respiratory substance is fully oxidized. Use of oxygen from atmosphere is obligatory. At its end H2o water and CO2 (carbon dioxide) are released. A large amount of energy is liberated. All higher organisms respire aerobically.
Anaerobic respiration:
In this anaerobic metabolism , this kind of respiration occurs in total absence of oxygen. During this, the respiration substance is incompletely oxidized, and other organic substances like ethyl alcohol, latic acid or aerobic acid are formed. CO2 is released. The amount of energy released is low. Anerobic respiration occurs in lower organisms like bacteria and fungi. However, even in higher organisms, anaerobic respiration can occur for short periods in the events of insufficient supply of O2. Anaerobic respiration is also called fermentation. The anaerobic respiration resulting in the production of ethanol can be represented as under:
C6H12O6 gives 2 CH3. CH2. OH + 2 CO2 + a little free energy.
