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

Question

Quizplus · Accepted Answer

The phosphorylation of cytoplasmic sensor proteins in chemotaxis regulation does not provide ATP for flagella rotation. Instead, it leads to a signaling cascade that alters the behavior of the flagella (e.g., changes in rotation or direction), but ATP or proton motive force directly powers flagellar rotation, not the phosphorylation events themselves.
