<prompt> In conversion of lactic acid to glucose, three reactions of glycolytic pathway are circumvented, which of the following enzymes do not participate?Pyruvate carboxylasePhosphoenol pyruvate carboxy kinasePyruvate kinaseGlucose-6-phosphatase  <response>: Ans. C. Pyruvate kinasePyruvate Kinase is the enzyme used in glycolysis. In the conversion of Lactic Acid to glucose the three steps of glycolysis are made reversible. To convert pyruvate to PEP---Pyruvate carboxy kinase and PEP carboxy kinase are utilized.
