The Maximum P/O Ratio of FADH₂ is __________

Question

The maximum P/O ratio of FADH2is __________.
A) 1.5
B) 1.75
C) 2.0
D) 2.5
E) 3.0

Accepted Answer

The P/O ratio for FADH2 (as indicated by "FADH₂") is 1.5 because it enters the electron transport chain at a point that results in fewer ATP molecules being produced compared to NADH. Specifically, FADH2 donates electrons to complex II, bypassing complex I, and thus generates fewer ATPs per molecule oxidized.
