Chemotaxis

7. Prokaryotic Cell Structures & Functions / Chemotaxis / Problem 4

In the context of bacterial chemotaxis, how does the concentration of the phosphorylated CheY protein influence the direction of flagellar rotation?

A

High levels of phosphorylated CheY cause counterclockwise rotation, leading to smooth swimming.

B

Low levels of phosphorylated CheY cause clockwise rotation, leading to tumbling.

C

High levels of phosphorylated CheY cause clockwise rotation, leading to tumbling.

D

Phosphorylated CheY does not affect flagellar rotation but influences the cell’s metabolism.
