    Net gain of ATP molecules, during aerobic respiration, is:

    A)  30 molecules                    

    B)  38 molecules    

    C)  40 molecules    

    D)         48 molecules

    Correct Answer: B

    Solution :

    38 ATP molecules are yielded during aerobic respiration of glucose but in most eukaryotic cells, 2ATP molecules are expended in transporting, 2NADH molecules produced in glycolysis to the mitochondria. In such a cell there is a net gain of 36ATP molecules instead of 38.
