Question

Quizplus · Accepted Answer

The proton motive force indeed involves a pH gradient component, as it is generated by the movement of protons (H+) across a membrane, creating a gradient. This force can also be used for active transport processes, such as the uptake of nutrients or the expulsion of waste products, by harnessing the energy stored in the gradient.
