Glucose finally metabolized to CO2 and water in (AIIMS May 2007)

 

 
A Cytosol
B Mitochondria

 

C Nucleus
D ER

 

 

 

Ans. B Mitochondria
  1. Regarding glucose metabolism, glycolysis, the pathway which converts glucose to two molecules of pyruvate takes place in cytoplasm.
  2. Once pyruvate is formed, it will be taken up by the mitochondria where the final pathway of complete oxidation of it to CO2 and water occurs in two steps:
  3. Pyruvate dehydrogenase converts pyruvate to acetyl CoA
  4. Acetyl CoA will then enter into TCA cycle giving rise to CO2 and water.
  5. Thus, for the above question, the answer is mitochondria.
