WebThe first step in gluconeogenesis is the conversion of pyruvate to phosphoenolpyruvate, which happens in two steps. In the first step, pyruvate is converted to oxaloacetate by … WebThe first step is converting pyruvate to phosphoenolpyruvate, or PEP - but this is also our first roadblock. In glycolysis, the enzyme pyruvate kinase catalyzes PEP turning into pyruvate, but not vice versa. The alternate route involves 3 enzymes; pyruvate carboxylase, malate dehydrogenase, and phosphoenolpyruvate carboxykinase, or PEPCK. signed aguero shirt
