uni·port·er (uґnĭ-port-ər) a cell membrane transport protein that facilitates the passage of small hydrophilic ions and molecules through a cell membrane down a concentration gradient. See also facilitated diffusion, under diffusion.Medical dictionary. 2011.
Uniporter — A uniporter is an integral membrane protein that is involved in facilitated diffusion. They can be either a channel or a carrier protein.Uniporter carrier proteins work by binding to one molecule of solute at a time and transporting it with the… … Wikipedia
Symporter — How it works A symporter is an integral membrane protein that is involved in movement of two or more different molecules or ions across a phospholipid membrane such as the plasma membrane in the same direction, and is therefore a type of… … Wikipedia

Passive transport — means moving biochemicals and other atomic or molecular substances across membranes. Unlike active transport, this process does not involve chemical energy, because, unlike in an active transport, the transport across membrane is always coupled… … Wikipedia
Membrane transport — In cellular biology the term membrane transport refers to the collection of mechanisms that regulate the passage of solutes such as ions and small molecules through biological membranes namely lipid bilayers that contain proteins embedded in them … Wikipedia
Antiporter — An antiporter (also called exchanger or counter transporter) is an integral membrane protein which is involved in secondary active transport of two or more different molecules or ions (i.e. solutes) across a phospholipid membrane such as the… … Wikipedia
