What are the different ways in which glucose is oxidised to provhave with regard to obtaining oxygen for respiration?energy in various organisms? |

Answer» aquatic organisms get oxygen in dissolved which makes them difficult to respire while terrestrial organisms inhale oxygen directly from environment There are two different ways in which glucose is oxidised:1)aerobic repiration(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)anerobic repiration(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. |
