Question

Assertion : Complex II and complex III of ETS are NADH dehydrogease and cytochrome oxidase complex respectively.
Reason : Cytochrome c acts as a mobile carrier for transfer of electrons between complex II and III.
A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false

Answer 1

Correct Answer - d
Complex II of ETS is succinate dehydrogenase complex and compex III of ETS is cytochrome `bc_(1)` comples. Cytochrome c is a small protein attached to the outer surface of inner mitochondrial membrane and acts as a mobile carrier for transfer of electrons between complex III and IV.
