First step of gluconeogenesis
WebJun 6, 2024 · The first step involves pyruvate carboxylase (PC), a ligase that adds a carboxyl group on pyruvate to create oxaloacetate. The enzyme consumes one ATP molecule, uses biotin (vitamin B7) as a cofactor, and … 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.
