Out of 36 ATP molecules produced per glucose molecule during respirati...
Explanation:
During cellular respiration, glucose is oxidized to produce ATP. The process of ATP production occurs in three stages: glycolysis, the Krebs cycle (also known as the citric acid cycle), and the electron transport chain.

- Glycolysis produces a net of 2 ATP molecules per glucose molecule.
- The Krebs cycle produces 2 ATP molecules per glucose molecule.
- The electron transport chain produces 32-34 ATP molecules per glucose molecule.

Therefore, the total ATP yield per glucose molecule is 36-38 ATP molecules.

Option B is the correct answer because it states that 2 ATP molecules are produced outside the mitochondria, during glycolysis, and the remaining 34 ATP molecules are produced inside the mitochondria, during the Krebs cycle and the electron transport chain.

Other options are incorrect because:

- Option A states that 2 ATP molecules are produced outside glycolysis, which is incorrect because all ATP molecules produced during cellular respiration are formed inside the cell.
- Option C states that 2 ATP molecules are produced during glycolysis and 34 during the Krebs cycle, which is incorrect because the electron transport chain also produces ATP molecules.
- Option D states that all ATP molecules are formed inside the mitochondria, which is incorrect because 2 ATP molecules are produced during glycolysis, which occurs in the cytoplasm, outside the mitochondria.

Read the passage given below and answer the following questions:Adenosine triphosphate (ATP) is the energy carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes. ATP is a nucleotide that consists of three main structures: the nitrogenous base, adenine; the sugar, ribose; and a chain of three phosphate groups bound to ribose. The phosphate tail of ATP is the actual power source which the cell taps. Available energy is contained in the bonds between the phosphates and is released when they are broken, which occurs through the addition of a water molecule (a process called hydrolysis). Usually only the outer phosphate is removed from ATP to yield energy; when this occurs ATP is converted to adenosine diphosphate (ADP), the form of the nucleotide having only two phosphates.The importance of ATP (adenosine triphosphat e) as the main source of chemical energy in living matter and its involvement in cellular processes has long been recognized. The primary mechanism whereby higher organisms, including humans, generate ATP is through mitochondrial oxidative phosphorylation. For the majority of organs, the main metabolic fuel is glucose, which in the presence of oxygen undergoes complete combustion to CO2 and H2O: C6H12O6 + 6O2 → 6O2 + 6H2O + energyThe free energy (ΔG) liberated in this exergonic (ΔG is negative) reaction is partially trapped as ATP in two consecutive processes: glycolysis (cytosol) and oxidative phosphorylation (mitochondri
