NEET Biology question

Fermentation is represented by the equation

(A)C6H12O6 + 6O2 → 6CO2 + 6H2O + 686 kcal
(B)C6H12O6 → 2C2H5OH + 2CO2 + 59 kcalCorrect
(C)6CO2 + 12H2O --(Light, Chlorophyll)--> C6H12O6 + 6H2O + 6O2
(D)C6H12O6 → C6H12O6 + 6O2

Answer: (B)

Solution

Alcoholic fermentation of one glucose molecule yields 2 ethanol + 2 CO2, releasing only about 59 kcal (far less than the ~686 kcal released by complete aerobic oxidation, since
