The following are cellular processes that can be directly powered by the proton motivo force ( $ \Delta $ p), EXCEPT
A) ATP biosynthesis from ADP and Pi.
B) flagellar rotation.
C) nutrient uptake.
D) drug efflux in some pathogens.
E) protein biosynthesis.

Question

Quizplus · Accepted Answer

Protein biosynthesis is not directly powered by the proton motive force. Instead, it requires the energy from GTP hydrolysis. The other options (ATP biosynthesis, flagellar rotation, nutrient uptake, and drug efflux) all require the energy from the proton motive force.
