Question

Quizplus · Accepted Answer

The bacterial flagellum is turned by a motor that uses energy from a proton motive force, created by the transfer of protons across the bacterial cell membrane by electron transport chains. This process generates the energy required for flagellar rotation. ATP, glucose, phosphoenolpyruvate, and AMP are all sources of energy used within cells, but they are not directly involved in the rotation of the bacterial flagellum.
