Biology / Unit 2 Bio 0366 short lesson, about 20 seconds
Uniporters, Symporters, and Antiporters
Captions available
The idea
A uniporter carries one substance; a symporter carries two substances the same direction; an antiporter carries two in opposite directions.
In practice
The sodium-potassium pump from Bio 0362 is an antiporter, moving sodium and potassium opposite ways across one membrane.
Where people slip
These terms describe direction and count, independent of whether the transport is active or facilitated.
