What are the different ways in which glucose is oxidised to provide energy in various organisms

Answer»

There are two different ways in which glucose is oxidized:
1)AEROBIC Respiration(oxygen)BREAKING down of PYRUVATE using oxygen takes place in MITOCHONDRIA. This process breaks up the three-carbon pyruvate molecule to give three MOLECULES of carbon dioxide. This process is done in presence of oxygen.
2)Anaerobic Respiration(without oxygen)the breaking of six carbon molecule, into three-carbon molecule called pyruvate. This process takes place in cytoplasm. Further, the pyruvate may be converted into ethanol and carbon dioxide. This process is done in absence of oxygen.
