alleryThe number of ATP molecules produced per NADH oxidised in ETS is
A3 ATP per NADH oxidised
B2 ATP per NADH oxidised
C1 ATP per NADH oxidised
D0 ATP per NADH oxidised
Answer & Solution
Correct answer: A. 3 ATP per NADH oxidised
NADH delivers electrons at Complex I
pumping at I, III and IV moves enough protons to make 3 ATP.
FADH2 enters at Complex II (bypasses Complex I) and yields only 2 ATP per molecule.
