  • 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

  • I. Proton channel of oxysome / complex V / ATP synthase is located in F_(0) II. Metabolic water is water produced in terminal oxidation / produced in respiration III. CoQ accept electron from NADH dehydrogenase (complex) and also can accept electron from FADH_(2) / succinate Q-reducatase / complex II IV. Cytochrome c is a small protein attached to outer surface of the inner mitochondrial membrane and acts as a mobile carrier for transfer of electrons between complex III (Cyt bc, comlex) and IV V. Complex IV refers to cytochorme c oxidase (cyta a, a_(3) and 2 Cu per centre) VI. If a cell is treated with a drug that inhibits ATP synthase, the pH of mitochondrial matrix will increase

    A
    All are correct
    B
    All are incorrect
    C
    I and V are correct
    D
    Only III is correct
