Question

How many molecules of ATP are produced per molecule of $FAD{H}_2$ oxidised?

• A. One
• B. Two
• C. Three
• D. Four

Answer 1

The correct option is B Two

• Oxidative phosphorylation in mitochondria produces ATP. The number of ATP molecules synthesized depends on the nature of the electron donor.
• Oxidation of one molecule of $NAD{H}_2$ gives rise to 3 molecules of ATP, while that of one molecule of $FAD{H}_2$ produces 2 molecules of ATP.
  Hence, the correct option is B.
