The 19 pages that link to Active transport, each with the reason it gives.

• ATPRelated: ATP directly powers pumps that maintain essential concentration gradients.

• Salt glandRelated: Salt-secreting cells use energy-dependent ion transport to move salts into glandular fluid.

• Membrane proteinRelated: Transport proteins use energy to move substances uphill across membranes.

• Plasma membraneRelated: It maintains ion and solute distributions that passive movement would otherwise dissipate.

• CellRelated: Cells use active transport to accumulate or expel substances against gradients.

• ChemiosmosisRelated: Chemiosmosis can power active transport by coupling downhill ion flow to uphill movement of another solute.

• Membrane transportRelated: It moves solutes uphill when passive transport cannot establish the needed distribution.

• Epithelial cellsRelated: It powers selective epithelial uptake and release of ions and nutrients.

• Cell Physiological PhenomenaRelated: It lets cells build gradients needed for uptake, signaling, and electrical activity.

• Transport (biology)Related: It moves substances in directions that diffusion alone would oppose.
