Answer
Complex II – Succinate Dehydrogenase
Complex II of the mitochondrial electron transport chain is known as Succinate Dehydrogenase.
- It plays a dual role in both the Krebs cycle and the electron transport chain.
- The enzyme catalyzes the oxidation of succinate to fumarate in the Krebs cycle.
- It also transfers electrons to ubiquinone (coenzyme Q), aiding in electron transport.
