The half-life of the activated pheromone–PBP–receptor complex (t1/2FAR′) may be determined from the steady dose–response curve (a) and from the fall of the receptor-potential after stimulus offset (b). We assume that the relationship between the amplitude of the potential and the concentration FAR′ is the same during transients as in the steady state (see text). Thus, from the steady dose-response curve we may find the mV-amplitude at which the concentration of FAR′ falls to half of its “steady” value. This amplitude is reached at t1/2FAR′ after stimulus offset
