Question

When 12H⁺ pass through $F_{0-}{F}_1$ particle, how many $\text{ATPs}$ are produced?

• A. 6 ATP
• B. 4 ATP
• C. 8 ATP
• D. 10 ATP

Answer 1

Answer: (A)

The energy released during the electron system is utilized in synthesizing ATP with the help of ATP synthase enzyme (complex V). This complex consists of two major components: $F_1$ and F0. For each ATP produced, 2H⁺ pass through $F_0$ from the intermembrane space to the matrix down the electrochemical proton gradient.
