The alternative to active transport is passive transport, which uses kinetic energy only to move the molecules. Passive transport can only move molecules from a region of higher concentration to lower ...

Active transport is a process that moves molecules against a concentration gradient. The process requires energy. For plants to take up mineral ions, ions are moved by active transport into root hairs ...

(Nanowerk Spotlight) Nanofluidic channels feature a unique unipolar ionic transport when properly designed and constructed. Recent research in nanofluidics has adopted reconstructed layered ...
