alleryDuring the electron transfer chain reaction, how many molecules of ATP are obtained from each molecule of NADH2?
AThree
BFour
COne
DTwo
Answer & Solution
Correct answer: A. Three
1. NADH2 and FADH2 participate in the electron transfer chain reaction.
2. Each NADH2 molecule yields 3 molecules of ATP.
3. Each FADH2 yields only 2 ATP, so the value two belongs to FADH2 and is ruled out.
