Which statement BEST explains why the P/O ratio for NADH is higher than that of FADH2?
Which statement BEST explains why the P/O ratio for NADH is higher than that of FADH2?
The redox pair NAD+/NADH has a higher affinity for electrons than the redox pair FAD/FADH2 therefore more ATP can be produced from NAD+/NADH. Electrons traveling through the ETC from NADH contribute more protons to the gradient than FADH?2?. The transfer of electrons from FADH?2? to complex II loses more energy as heat compared to the transfer of electrons from NADH to complex I. NADH donates more electrons per molecule than FADH?2Explanation / Answer
Option C is correct .
The transfer of electrons from FADH2 to complex II loses more energy as heat compared to the transfer of electrons from NADH to complex I.
NADH gives up its electron to Complex I which is at higher energy level whereas FADH2 gives up its electron to complex II by passing complex I. Energy is given off when complex I transfer to complex III and hence pumping electrons across the membrane. These electrons then moves to complex IV hence pumping even further more electrons.
