In the electron transport system present in the inner mitochondrial membrane complexes I and IV are respectively

Options

A. NADH dehydrogenase and `FADH_(2)`
B. `FADH_(2)` and `NADH` dehydrogenase
C. `NADH` dehydrogenase and cytochrome c oxidase complex
D. NADH dehydrogenase and ATP synthase

Answer

C

Explanation

Four major respiratory enzyme complexes of electron transport chain are located in the inner mitochondrial membrane :
Complex I (NADH dehydrogenase), complex II (succinate dehydrogenase), complex II (cytochrome bc), and cytochrome IV (cytochrome c oxidase)
There is a fifth complex called ATP synthase which is involved in ATP synthesis.
