The proton motive force drives the following process in bacteria:
A) ATP biosynthesis from ADP and Pi
B) flagellar rotation
C) nutrient uptake
D) all of the above
E) none of the above

Question

Quizplus · Accepted Answer

The proton motive force is generated by the electron transport chain, which pumps protons across the membrane to create an electrochemical gradient. This gradient can be used to drive the synthesis of ATP from ADP and Pi (choice A), as well as to power the rotation of flagella (choice B) for motility and the active transport of nutrients (choice C) across the membrane. Therefore, the correct answer is D, all of the above.
