gradient /gra·di·ent/ (gra´de-ent) rate of increase or decrease of a variable value, or its graphic representation.
gradient
gradient [gra´de-ent]
electrochemical gradient a difference in ion concentration between two points so that ions tend to move passively along it.
gra·di·ent (gr  d - nt)n. 1. The rate at which a physical quantity, such as temperature or pressure, changes relative to change in a given variable, especially distance. 2. A series of progressively increasing or decreasing differences in the growth rate, metabolism, or physiological activity of a cell, an organ, or an organism. |
gradient
[grā′dē·ənt]
Etymology: L, gradus, step
1 the rate of increase or decrease of a measurable phenomenon, such as temperature or pressure.
2 a visual representation of the rate of change of a measurable phenomenon; a curve.
gradient [gra´de-ent]
rate of increase or decrease of a variable value, or its representative curve.

electrochemical gradient the difference in ion concentration and electrical potential from one point to another, so that ions tend to move passively along it.
gradient
rate of increase or decrease of a variable value.
