Fig. 3. Changes in the input resistance and the membrane potential of a membrane
vesicle derived from the contractile vacuole complex of a P.
multimicronucleatum cell accompanied by images of the vesicle's
rounding-slackening. (Ai, Bi) Frames of two different vesicles showing
rounding and slackening. Rounding of the vesicle is recognizable by the
enhanced shadow effect (maximum rounding in Ai is in e and in Bi is
in g before bursting in h). (Aii, Bii) Time courses of
change in the input resistance, Rm, for the vesicles.
(Aiii, Biii) Time courses of change in the membrane potential,
Vm, for the vesicles. (ah) in Ai and Bi
correspond to the sequence when each picture was taken, which is also
indicated by short vertical bars marked by the letters on the traces for
Rm (Aii, Bii) and Vm (Aiii, Biii). e,
patch-clamp electrode; n, microneedle; v, membrane vesicle. Scale bars, 50
µm.
