Question
In the section dealing with “NAD+ in disease” it is mentioned that metabolomics results
indicate that impaired mitochondrial function contributes to some of the mentioned
diseases. Which metabolites can potentially accumulate when complex I of the
electron transport chain is defective? Use Fig 1 for guidance
Expert Solution
Step 1
Complex I is the first enzyme of the respiratory chain. It oxidizes NADH, which is generated through the Krebs cycle in the mitochondrial matrix and uses the two electrons to reduce ubiquinone to ubiquinol. It is the largest and least understood component of the mitochondrial oxidative phosphorylation system.
