Bacteria Do Not Respond Directly to a Concentration Gradient by Curving

question 7

Essay

Bacteria do not respond directly to a concentration gradient by curving their trajectory toward an attractant; instead, they tumble (randomly switch directions) unless inhibited from doing so. How do larger organisms navigate toward the source of a chemoattractant? With which other sensory system might we expect to see parallels in circuitry organization?
