Read the following statements and choose option which contain wrong statement for electron transport system :
(i) Electrons from NADH produced in the mitochondrial matrix during citric acid cycle are oxidised by an NADH dehydrogenase (complex I).
(ii) Electrons are then transferred to ubiquinone located within the inner membrane.
(iii) Ubiquinone also receives reducing equivalents via FADH₂ (complex II) that is generated during oxidation of succinate in the citric acid cycle.
(iv) Ubiquinone (ubiquinol) is oxidised with the transfer of electrons to cytochrome b via cytochrome be, complex (complex III).
(v) Cytochrome b is a small protein attached to the outer surface of the inner membrane and acts as a mobile carrier for transfer of electrons between complex III and IV.
(vi) Complex IV refers to cytochrome c oxidase complex containing cytochromes a and a3 and two copper centres.
(vii) When the electrons pass from complex I to IV coupled to ATP synthase (complex V) for the production of ATP from ADP and inorganic phosphate.
