Question

It is estimated that each electron pair donated by NADH leads to the synthesis of approximately three ATP molecules, whereas each electron pair donated by $\mathrm{FADH}_{2}$ leads to the synthesis of approximately two ATP molecules. What is the underlying reason for the difference in yield for electrons donated by $\mathrm{FADH}_{2}$ versus NADH?

Step 1

There are four complexes involved in this process: Complex I, Complex II, Complex III, and Complex IV. As electrons flow through these complexes, hydrogen ions are pumped out of the matrix into the intermembrane space. Show more…
