Which of the Following Describes a Correct and Complete Electron

Question

Which of the following describes a correct and complete electron transfer pathway?
A)NADH $\to$ complex I $\to$ CoQ $\to$ complex III $\to$ cyt c $\to$ complex IV
B)NADH $\to$ complex I $\to$ complex II $\to$ CoQ $\to$ complex III $\to$ cyt c $\to$ complex IV
C)NADH $\to$ complex I $\to$ cyt c $\to$ complex III $\to$ CoQ $\to$ complex IV
D)FADH2$\to$ CoQ $\to$ complex II $\to$ complex III $\to$ cyt c $\to$ complex IV
E)FADH2$\to$ complex II $\to$ cyt c $\to$ complex III $\to$ CoQ $\to$ complex IV

Accepted Answer

The correct pathway for electron transfer in the electron transport chain starts with NADH donating electrons to Complex I, then to Coenzyme Q (CoQ), followed by Complex III, cytochrome c (cyt c), and finally Complex IV. This sequence accurately reflects the flow of electrons from NADH through the main components of the electron transport chain to ultimately reduce oxygen to water.
