We provide a framework to study an effect of fluctuations in intracellular biochemical networks responsible for adaptation dynamics of bacteria. We use a 4 state chemoreceptor model, and investigate the dynamics and fluctuation. Analyzing fluctuation induced by extrinsic noise, we show a crucial relationship between the adaptation dynamics and the fluctuation; Adaptation precision of the system can be described by two quantities, normal fluctuation and irreversible circulation. This theorem means that we can predict how precisely bacteria adapt against external stimuli, by measuring state fluctuation of the chemoreceptor, without directly giving stimuli to them.
