uniport
This term is used exclusively within the fields of biochemistry and cellular biology to describe a specific mode of membrane transport. It is characterized by the movement of a single solute species across a cell membrane, distinguishing it from symport or antiport mechanisms where multiple species are moved simultaneously.
In a technical context, the term is typically used as a noun to describe the process or the protein channel facilitating the movement. It carries a neutral, scientific register and is rarely encountered outside of academic or medical literature.
Meanings
Examples
The glucose transporter GLUT1 operates via uniport to move sugar into the cell.
Is this a case of uniport or is there a second ion involved in the movement?
Uniport allows a single solute to move down its concentration gradient.
I wonder if this specific protein uses uniport to maintain intracellular balance.
The membrane protein facilitates the uniport of potassium ions.
Unlike symport, uniport does not require a co-transported molecule.
The rate of uniport depends heavily on the saturation of the carrier protein.
We need to determine if the transport mechanism is a simple uniport.
