How is chemotaxis regulated?

Question

Quizplus · Accepted Answer

Chemotaxis is regulated by a series of signal transduction events, in which specific receptors on the cell surface bind to chemical signals and trigger a cascade of intracellular responses that ultimately result in directed movement towards or away from the signal source. This process involves a coordinated set of changes in cytoskeletal dynamics, ion channels, and other cellular components that are regulated by the activity of a variety of signaling proteins and enzymes. While changes in gene expression can also play a role in modulating chemotactic responses over longer time scales, the immediate regulation of chemotaxis primarily involves complex signaling pathways that operate at the level of post-translational modifications and protein-protein interactions.
