Effect of Cyanide on the Plasmalemma Potential of Mnium1

AUTOR(ES)
RESUMO

By centrifuging Mnium cuspidatum leaf cells, the cytoplasm can be distinguished from the vacuole and a microelectrode tip can be located unambiguously in the cytoplasm. The site of the electrogenic pump is clearly demonstrated to reside in the plasmalemma as shown by depolarization of the cell electropotential induced by CN−.
