Fig. 2. Doseresponse curves of the effects of (A) cyanide (KCN) and (B)
dinitrophenol (DNP) on the basolateral membrane voltage
(Vbl, solid line) and the input resistance
(Rpc, broken line) of principal cells of Malpighian
tubules of the yellow fever mosquito Aedes aegypti. EC50
is the concentration at half-maximum response. Values from 6-14 principal
cells (in parentheses) are shown.
