Question

A false statement regarding cytochrome c-oxidase complex in ETS in mitochondria is (A) Receives electrons directly from ubiquinone (B) Capable of reducing O 2 (C) Extend across the thickness of inner mitochondrial membrane (D) Contains Fe Cu both

Tardigrade Admin · Accepted Answer

Receives electrons directly from ubiquinone via cyt bc1 to cyt c. i.e., U Q arrow cyt bc 1 arrow cyt c

Q. A false statement regarding cytochrome c-oxidase complex in ETS in mitochondria is

Receives electrons directly from ubiquinone

Capable of reducing $O_{2}$

Extend across the thickness of inner mitochondrial membrane

Contains Fe & Cu both

Receives electrons directly from ubiquinone via $cy t b c 4$ to $cy t c$ .
i.e., $U Q \to cy t b c_{1} \to cy t c$
