<prompt> The following is an enzyme required for glycolysis:Pyruvate kinasePyruvate carboxylaseGlucose-6-phosphataseGlycerokinase  <response>: Phosphoenol pyruvate PEP is dephosphorylated to pyruvate, by pyruvate kinase. First PEP is made into a transient intermediary of enol pyruvate; which is spontaneously isomerized into keto pyruvate, the stable form of pyruvate.Reference: Vasudevan 7th ed, pg 108
