Expert Solution

The electron transport chain (ETC) is the major consumer of O2 in mammalian cells. The ETC passes electrons from NADH and FADH2 to protein complexes and mobile electron carriers. Coenzyme Q (CoQ) and cytochrome c (Cyt c) are mobile electron carriers in the ETC, and O2 is the final electron recipient.

Some compounds like succinate, which have more positive redox potential than NAD+/NADH can transfer electrons via a different complex—complex II. Coenzyme Q, or simply Q, can travel within membrane while Cyt C is a soluble protein. Flavoproteins are components of complexes I and II and Fe-S is present in complexes I, II, and III. The Fe atom present in Fe-S complexes helps in electron transfer by shifting from Fe2+ to Fe3+ states.

IF SINGLE OPTION IS ONLY CORRECT THEN CHOOSE CYTOCHROME C IF MULTIPLE ARE CORRECT THEN GO FOR CYTOCHROME C AND Fe-S CLUSTER

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?

In the electron-transport chain, electrons are handed off from low reduction potential carriers to increasingly higher reduction potential carriers. At some steps this exchange of electrons is sufficiently exergonic to drive proton pumping. Based on this, explain why FADH2 results in less ATP generation per mole compared with NADH.
