Question

In mitochondria, synthesis of ATP uses a proton motive force that is used to

Answer 1

Answer:

The correct answer will be option-B.

Explanation:

The ATP synthase is the multi-complex enzyme which helps in the formation of  ATP molecules. The ATP synthase consists of two subunits- F₀ and F₁ in which F₁ unit contains α, β, and γ subunit which rotates and changes the conformation of the β subunit. The β subunit cycles in three states- O - open,  L - loose and T - tight conformation.

The flow of protons binds the ADP and Pi to L state and O becomes L. Later the ATP is released out when T changes to O state.  

Thus, the proton motive force causes the condensation of ADP and Pi to form ATP and Option-B is the correct answer.
