What are the enzymes required for the formation of Phosphoenolpyruvate from Pyruvate?

Ans. is 'c' i.e., Pyruvate carboxylase and Phosphoenolpyruvate CarboxykinasePyruvate conversion to Phosphoenol pyruvate is a pa of gluconeogenesis, Pyruvate is conveed to Oxaloacetate by Pyruvate Carboxylase, Pyruvate Carboxylase requires Biotin as coenzyme. It uses Carbondioxide in the form of Bicarbonate. It uses ATP as a source of energy.
