Nernst Equation
... The Nernst equation gives a formula that relates the numerical values of the concentration gradient to the electric gradient that balances it ... For example, if a concentration gradient was established by dissolving KCl in half of a divided vessel that was originally full of H2O, and then a membrane permeable to K+ ions was ...

Glucose Uptake - Secondary Active Transport
... Facilitated diffusion can occur between the bloodstream and cells as the concentration gradient between the extracellular and intracellular environments is such that no ATP hydrolysis is required ... from the filtrate in the tubule lumen, where it is at a relatively low concentration, passes through the simple cuboidal epithelia lining the kidney tubule, and into the ... Therefore the concentration gradient of glucose opposes its reabsorption, and energy is required for its transport ...

Passive Transport - Diffusion (Simple)
... the net movement of material from an area of high concentration to an area with lower concentration ... The difference of concentration between the two areas is often termed as the concentration gradient, and diffusion will continue until this gradient has been eliminated ... diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient" (compared with active transport, which ...
