In the electron transport system, the final acceptor of proton is
1 cytochrome b
2 cytochrome \(a_{3}\)
3 oxygen
4 ubiquinone (substance A)
Explanation:
In the electron transport system, the final acceptor of proton is oxygen. Oxygen functions as the terminal acceptor of electrons and is reduced to water along with the hydrogen atoms in mitochondrial matrix. It drives whole process by removing hydrogen from system.

Assertion : Complex II and complex III of ETS are NADH dehydrogenase complexes Reason : Cytochrome c, acts as a mobile carrier for transfer of electrons between complex II and III
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Complex II of ETS is succinate dehydrogenase complex, complex III is cytochrome bc1 complex. Cytochrome \(\mathrm{c}\) is protein attached to the outer surface of inner mitochondrial membrane, it acts as an electron carrier for transfer between complex III and complex IV.
