The Non-correlation of Bioelectric Potentials with Ionic Gradients
The sartorius muscles of 320 toads have been analyzed for Na(+) and K(+). There is a wide variation in the Na(+) content which when calculated intracellularly varied from 0 m.eq./kg. to 58 m.eq./kg. In particular it was found that the distribution of internal Na(+) in the intact animal was such that only 17 per cent of the muscles should give from the Nernst equation the observed overshoot of 3...
متن کاملThe Generation of Bioelectric Potentials
EVER since Matteucci and DuBois Reymond established the fact that muscle and nerve activity is associated with bioelectric, potentials, it has been safe to assume that contraction of the heart must also have an electric correlate. Although Koelliker and Johannes Mueller actually were the first to succeed in demonstrating such electric activity, it was only when Einthoven, using a sufficiently s...
متن کاملCalculations of Bioelectric Potentials
Interest in the study of Halicystis and of Valonia has been stimulated by discoveries of marked contrasts and striking similarities existing side by side. This is illustrated by new experiments with the alkali metals and alkaline earths. In Halicystis the apparent mobilities of K(+), Rb(+), Cs(+), and Li(+) (calculated by means of Henderson's equation from changes in P.D. produced by replacing ...

متن کاملBioelectric Potentials in Valonia
In their influence on the P.D. across the protoplasm of Valonia macrophysa, Kütz., Li(+) and Cs(+) resemble Na(+), while Rb(+) and NH(4) (+) resemble K(+). The apparent mobilities of the ions in the external surface layer of Valonia protoplasm increase in the order: Cs(+), Na(+), Li(+) < Cl(-) < Rb(+) < K(+) < NH(4) (+).
