Question

One molecule of NADH and one molecule of $FAD{H}_2$ yield

• A. 2 and 3 ATP
• B. 18 and 36 ATP
• C. 36 and 18 ATP
• D. 3 and 2 ATP
• E. 2 and 36 ATP

Answer 1

The correct option is D 3 and 2 ATP

Reduced molecules like NADH+H+ and FADH2 yield energy in the form of ATP when they undergo ETC in mitochondria. NADH+H+ enter ETC at higher complex than FADH2 so they release energy as 3 ATP and 2 ATP respectively.

So the answer is '3 and 2 ATP'.
