Once cytoplasmic sensor proteins involved in chemotaxis regulation are phosphorylated,a cascade of other phosphate-transferring mechanisms provide ATP energy to rotate flagella.

Question

Quizplus · Accepted Answer

Phosphorylation in chemotaxis regulation does not directly provide ATP energy for flagella rotation; instead, it modulates the activity of motor proteins that use a proton motive force, not ATP, to rotate the flagella.
