Question

What are the different ways in which glucose is oxidised to provide energy various organisms? Please tell in long answer question (5 question)

Answer 1

Answer:

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.
