How many $CO_2$ molecules are released by the complete oxidation of $2$ molecules of glucose?

In prokaryotic cells,the net gain of $ATP$ molecules from one molecule of glucose during aerobic respiration is $.........$.

The net gain of energy,from one molecule of sucrose in aerobic respiration,is (in $ATP$)

If one molecule of $PEP$ (Phosphoenolpyruvate) is completely oxidized through the respiratory pathway starting from glycolysis,how many total $ATP$ molecules are synthesized?

Why is the respiratory balance sheet not considered logical?

Calculation of $ATP$ gain for every glucose is made on certain assumptions. Choose the correct option in accordance with the statement given above.
