    Four respiratory enzymes are given below. Arrange them in increasing order of the carbon number of the substrates on which they act (i) Enolase (ii)  aconitase (iii)  rumerase                                    (iv) alcohol dehydrogenase The correct order is

    A)  (ii), (iv), (iii), (i)                                

    B)  (iv), (i), (ii), (iii)

    C)  (i), (iv), (iii), (ii)                                

    D)  (iv), (i), (iii), (ii)

    Correct Answer: D

    Solution :

                     Enolase works on 2-phosphoglyceric acid (3C compound),   aconitase   on   citric   acid  (6C-compound), fumerase on furmaric acid (4C compound) and alcohol dehydrogenase on acetaldehyde (2C compound). Thus, increasing order of these enzyme based on the carbon number of the substrates on which they act is ? (iv), (i), (iii), (ii).
