kemotaktikkona
Kemotaktikkona is the directed movement of cells in response to chemical gradients. In biology, it describes how organisms—from single-celled bacteria to multicellular immune cells—navigate their environment by sensing attractants and repellents. Positive chemotaxis guides cells toward higher concentrations of a chemical, while negative chemotaxis drives movement away from it.
In bacteria such as Escherichia coli, kemotaktikkona is achieved through a run-and-tumble strategy modulated by receptors
In much of the eukaryotic world, kemotaktikkona involves surface receptors that detect chemoattractants and trigger intracellular
Chemotaxis relies on gradient sensing, which can be spatial (cells compare signals across their surface) or
Kemotaktikkona is essential for immune defense, wound healing, development, and microbial ecology. It drives neutrophil recruitment
