The proton motive force (PMF)across a cell membrane can be used for which of these processes?

Question

Quizplus · Accepted Answer

The proton motive force (PMF) can be used for all of the listed processes. The PMF is generated by the accumulation of protons (H+) on one side of the cell membrane, creating an electrochemical gradient. This gradient can be used to drive the production of ATP, by powering the ATP synthase enzyme. It can also be used to propel flagella, as the flagellar motor uses the PMF as a power source. Additionally, the PMF can be used to transport nutrients into the cell, by powering nutrient uptake transporters, and can be used to transport molecules out of the cell, by powering efflux transporters.
