Explanation
In fermentation the incomplete oxidation of glucose is achieved under anaerobic conditions by sets of reactions where pyruvic acid is converted to CO2 and ethanol. There is a net gain of only two molecules of ATP for each molecule of glucose. NADH is oxidised to NAD+ rather slowly in fermentation. In aerobic respiration complete oxidation of pyruvate by the stepwise removal of all the hydrogen atoms, leaving three molecules of CO2. In this more molecules of ATP are generated under aerobic conditions. The reaction is very vigorous in case of aerobic respiration.
