Question

Write a short note on uniport and symport transport

Answer 1

Answer:

Uniport (a single substance, moves in a single direction)

Symport (two substances, moves in the same direction)

Antiport (two substances, moves in opposite directions)

Explanation:

A uniporter is an integral membrane protein that transports a single type of substrate species (charged or uncharged) across a cell membrane. It may use either facilitated diffusion and transport along a diffusion gradient or transport against one with an active transport process..

A symporter is an integral membrane protein that is involved in the transport of many differing types of molecules across the cell membrane. ... Typically, the ion(s) will move down the electrochemical gradient, allowing the other molecule(s) to move against the concentration gradient

Uniporters, symporters, and antiporters are proteins that are used in transport of substances across a cell membrane. ... Symporters and antiporters are involved in active transport. Antiporters transport molecules in opposite directions, while symporters transport molecules in the same direction.
