Editing Chemoreceptor (section)

===In prokaryotes===
Bacteria utilize complex long helical proteins as chemoreceptors, permitting signals to travel long distances across the cell's membrane. Chemoreceptors allow bacteria to react to chemical stimuli in their environment and regulate their movement accordingly.<ref>{{Cite journal |last1=Samanta |first1=Dipanjan |last2=P.
