In the electron transport system present in the inner mitochondrial membrane, complexes I and IV are respectively
Options
- ANADH dehydrogenase and FADH 2
- BNADH 2 and NADH dehydrogenase
- CNADH dehydrogenase and cytochrome-c oxidase complex
- DNADH dehydrogenase and ATP synthase
Correct answer
C. NADH dehydrogenase and cytochrome-c oxidase complex
Step-by-step solution
Complex I of the electron transport system (ETS) is NADH dehydrogenase, which oxidizes NADH produced in the mitochondrial matrix during the citric acid cycle. Cytochrome c oxidase or complex IV catalyzes the final step in the mitochondrial electron transfer chain and is regarded as one of the major regulation sites for oxidative phosphorylation.
