Figure 5. Plots of dose-conductance functions.

Illustrate eqs. (2) and (3) for (A) the DAG-gated cationic conductance G _cat and (B) the Ca²⁺-gated Cl⁻ conductance G _Cl. The solid blue lines in A and B represent the conductance without inhibition. The EC₅₀ of the cationic current, K _mcat = 0.01 µM of DAG, is reached at U = 10^−4.25 µM/s, i.e. this current is most active at low pheromone uptakes. The EC₅₀ of the cationic current, K _mCl = 81 µM of Ca²⁺ corresponding to U = 50 µM/s, i.e. the Cl⁻ current is most active at high uptakes. The dashed red lines represent the conductance at half-maximum inhibition (intermediate curve) and maximum inhibition (rightmost curve) by CaCaM (A) and PKC* (B). The PKC* inhibition of the Cl⁻ current is very weak and practically negligible.
