c1 and c2 are the concentrations of the chosen planes, x1 - x0 is the distance between them. Since the concentration decreases with growing distance has the concentration gradient a negative value. If the formula is ... But it looses its significance when regarding whole tissues and ceases to have any effect at all when,

thereafter, sodium ions rush into the cell down their concentration gradient, reversing the internal polarisation of the cell from -70mV to +40mV. This in turn interferes with the resting potential of adjacent areas of membrane and may thus cause propagation of the action potential.

as gases diffuse into the bubble, surface area increases, which, in turn, increases the amount diffusing under a particular gas concentration gradient. ... a strong positive Pz may cause the bubble to reach its minimum size, beyond which it changes drastically or ceases to exist. Items in support of this possibility are the...

The purified protein appeared to exist as several oligomeric species. In an equilibrium retention assay ... However, the OmpF porin channel allowed influx of more solute molecules per unit time than did the equivalent weight of the OmpC porin when the flux was driven by a concentration gradient of the same size.
