    Enzyme enolase catalyses the conversion of 2 PGA to phosphoenol pyruvic acid in the presence of which of the following cofactors?

    A) \[M{{N}^{2+}}\]                    

    B) \[F{{e}^{2+}}\]

    C) \[M{{g}^{2+}}\]                     

    D) \[Z{{n}^{2+}}\]

    Correct Answer: C

    Solution :

    Conversion of 2 PGA to PEP is the 8th step of glycolysis. This conversion is catalysed by the enzyme enolase and takes place in the presence of cofactor \[M{{g}^{2+}}\] and \[{{R}^{+}}\] with the loss of a water molecule.
