Answer:
The enzyme that is similar to the pyruvate dehydrogenase complex is α-ketoglutarate dehydrogenase
Explanation:
Both enzymes have similarities, both structurally and functionally. Both enzymes are characterized by playing a primary role in the Krebs cycle. A characteristic of both enzymes is their ability to decarboxylate. The enzyme pyruvate dehydrogenase performs the decarboxylation process of pyruvate, while the enzyme alpha-ketoglutarate dehydrogenase performs the process of oxidative decarboxylation of alpha-keto acid compounds.
