WebNov 12, 2024 · The first step of gluconeogenesis involves the formation of oxaloacetate by the carboxylation of pyruvate (with the enzyme pyruvate carboxylase). OAA is then reduced to a molecule known as malate, which is then shuttled out of the mitochondrial membrane. Then, an enzyme known as malate dehydrogenase turns malate into … 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.
