NADH Dehydrogenase (Ubiquinone)

**Semantic type:** Amino Acid, Peptide, or Protein|Enzyme

**Definition:** A complex of over 40 proteins found in the inner mitochondrial membrane. This protein complex catalyzes the transfer of electrons from NADH to ubiquinone (coenzyme Q10) and plays a role in the initiation of the mitochondrial electron transport chain.
