Question

How many ATPs are produced when $12H^{+}$ pass through $F_0$ - $F_1$ particle?

• A. 2 ATP
• B. 4 ATP
• C. 6 ATP
• D. 5 ATP

Answer 1

Answer: (C)

The energy released during the electron system is utilized in synthesizing ATP with the help of the ATP synthase enzyme (complex V). This complex consists of two major components $F_1$ and $F_0$ . For each ATP produced, $2H^{+}$ passes through $F_0$ from the intermembrane space to the matrix down the electrochemical proton gradient. Hence, accordingly, if 12 H+ ions pass then 6 ATP is produced.
