The following two questions refer to the electron transport chain.

a. List, in correct order, the multiprotein complexes through which the electrons carried by NADH are moved. Name the molecule to which these electron are ultimately attached to.

b. List, in correct order, the multiprotein complexes through which the electrons carried by FADH₂ are moved. Name the molecule to which these electron are ultimately attached to.

Solutions

Expert Solution

Answer a

The correct order, the multiprotein complexes through which the electrons carried by NADH are moved is :

NADH Complex I (NADH Dehydrogenase) Coenzyme Q Complex III (Cytochrome bc1 complex) Cytochrome C Complex IV (Cytochrome C oxidase) O2 (oxygen molecule) Complex V (ATP synthase) for ATP synthesis.

Electrons are ultimately attached to oxygen molecule

Answer b

The correct order, the multiprotein complexes through which the electrons carried by FADH2 are moved is :

FADH2 Complex II (Succinate dehydrogenase) Coenzyme Q Complex III (Cytochrome bc1 complex) Cytochrome C Complex IV (Cytochrome C oxidase) O2 (oxygen molecule) Complex V (ATP synthase) for ATP synthesis

Electrons are ultimately attached to oxygen molecule

The electron transport chain has two diffusible electron carriers, ubiquinone, which shuttles electrons to the third mitochondrial complex, and cytochrome c, which shuttles electrons to the last mitochondrial complex (see figure below). Would it be possible for cells to use only one of these two diffusible electron carriers to shuttle electrons at each of these two steps of the electron transport chain? Why or why not?
