    Aerobic respiration produces more usable chemical energy than fermentation, because fermentation involves

    A) formation of lactic acid

    B) complete oxidation of food

    C) partial oxidation of food

    D) evolution of \[C{{O}_{2}}\] and alcohol

    Correct Answer: C

    Solution :

                    During aerobic respiration, complete oxidation of food takes place. Thus. during it a glucose molecule produces 36 ATP while during fermentation the food oxidises partially and instead of \[C{{O}_{2}}+{{H}_{2}}O\], formation of ethyl alcohol takes place with production of 2 ATP per glucose molecule.
