Chemical Restoration in Nitella: III. Effects of Inorganic Salts

Chemical Restoration in Nitella

Cells of Nitella exposed to distilled water lose their ability to produce action currents and to distinguish electrically between sodium and potassium. This ability was quickly restored by exposure to blood plasma deprived of calcium. Human blood and that of the cat, calf, and sheep gave essentially the same results. The active agents appear to be organic substances.

Arsenic, inorganic and soluble salts

Effects of Hexylresorcinol on Nitella

In some ways the effects of hexylresorcinol on Nitella resemble those of guaiacol but in others they differ. Both substances depress the P.D. reversibly and both decrease the potassium effect. Hexylresorcinol decreases the apparent mobility of Na(+) and of K(+). Guaiacol increases that of Na(+) but not of K(+). The action of hexylresorcinol is more striking than that of guaiacol since 0.0003 M ...

Restoration of Conductivity with TTFTCNQ ChargeTransfer Salts

The formation of the conductive TTF-TCNQ (tetrathiafulvalene– tetracyanoquinodimethane) charge-transfer salt via rupture of microencapsulated solutions of its individual components is reported. Solutions of TTF and TCNQ in various solvents are separately incorporated into poly(urea-formaldehyde) core–shell microcapsules. Rupture of a mixture of TTF-containing microcapsules and TCNQ-containing m...
