Question

In the electron transport system present in the inner mitochondrial membrane, complexes I and IV are respectively: (A) NADH dehydrogenase and FADH2 (B) FADH2 and NADH dehydrogenase (C) NADH dehydrogenase and cytochromec oxidase complex (D) NADH dehydrogenase and ATP synthase

Tardigrade Admin · Accepted Answer

Four major respiratory enzyme complexes of electron transport chain are located in the inner mitochondrial membrane :
Complex

I

(

N A DH

dehydrogenase), complex

II

(succinate dehydrogenase), complex

III

(cytochrome be,) and cytochrome

I V

(cytochrome

c

oxidase)
There is a fifth complex called

A TP

synthase which is involved in

A TP

synthesis.

Q. In the electron transport system present in the inner mitochondrial membrane, complexes $I$ and $I V$ are respectively:

$N A DH$ dehydrogenase and $F A D H_{2}$

$F A D H_{2}$ and $N A DH$ dehydrogenase

$N A DH$ dehydrogenase and cytochromec oxidase complex

$N A DH$ dehydrogenase and $A TP$ synthase

Cytochrome be $1$ complex and $N A DH$ dehydrogenase
