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

A) NADH Dehydrogenase and FAD$H_{2}$
B) NAD$H_{2}$ and NADH Dehydrogenase
C) NADH Dehydrogenase and cytochrome-c oxidase complex
D) NADH dehydrogenase and ATP synthase
Explanation

Complex I of electron transport system (ETS) is NADH dehydrogenase, which oxidase NADH produced in the mitochondrial matrix during citric acid cycle. Complex IV of cytochrome-and $a_{3}$ and two copper centres.
