The Proton Motive Force Is

Question

The proton motive force is
A) ATP synthase.
B) the proton concentration gradient and electric charge difference.
C) a metabolic pathway.
D) a redox reaction.
E) the movement of electrons across the membrane.

Accepted Answer

The proton motive force is the combination of the proton concentration gradient (difference in proton concentration on either side of a membrane) and the electric charge difference (positive outside, negative inside). This force is used to power the production of ATP by ATP synthase.
