Explanation:
During cellular respiration, glucose is broken down to produce ATP (adenosine triphosphate), the energy currency of the cell. The process involves three main stages: glycolysis, Krebs cycle, and respiratory chain.
Out of 36 ATP molecules produced per glucose molecule during respiration, 2 are produced outside mitochondria and 34 inside mitochondria. The breakdown of ATP molecules can be explained as follows:
1. Glycolysis:
During glycolysis, a glucose molecule is broken down into two pyruvate molecules, producing a net of 2 ATP molecules per glucose molecule. However, these ATP molecules are produced outside the mitochondria, in the cytoplasm of the cell.
2. Krebs cycle:
The pyruvate molecules generated during glycolysis enter the mitochondria and undergo further breakdown in the Krebs cycle. This cycle produces 2 ATP molecules per glucose molecule, but these ATP molecules are produced inside the mitochondria.
3. Respiratory chain:
The final stage of cellular respiration is the respiratory chain, which occurs in the inner membrane of the mitochondria. This process involves the transfer of electrons from NADH and FADH2 molecules to oxygen, producing a proton gradient that drives the synthesis of ATP. The respiratory chain produces 30 ATP molecules per glucose molecule, all of which are produced inside the mitochondria.
Therefore, out of 36 ATP molecules produced per glucose molecule during respiration, 2 are produced outside the mitochondria (during glycolysis) and 34 are produced inside the mitochondria (2 during Krebs cycle and 30 during respiratory chain).
Conclusion:
Option B is the correct answer as it accurately describes the location of ATP production during cellular respiration.

This is because glycolysis occurs outside mitochondria and intermediate pathway and Krebs cycle occurs inside mitochondria....
